    Good also to be able to have advance in-car warning of all those danger
    areas where they have decided to place safety cameras. ( That
    sentence may get me some flak.)

    Hooray! A sensible person who realises speed cameras are not to catch
    speeders but are to make people slow down for hazardous road conditions
    (adverse camber, hidden dips), or hazardous situations (schools). I am
    all for speed cameras in places where they serve a useful purpose, it
    just so happens that the camera location databases also include the
    money grabbing non-useful ones too.

    On-topic, I recently purchased a Foretrex 201 (one of the wrist ones),
    and in conjunction with my (slightly illegal) memory map software and
    the rather nice SportTracks it's become a necessity on all my Muni
    rides locally.

    Yes, although the police do not agree with you: I have been told they
    have just won the right to be able to camouflage cameras from sometime
    in 2007. The motive there would SEEM to be that, at those sites, they
    do not want the yellow box to be one more inducement to slow down:
    financial then. They also don't have to have had the prescribed number
    of nearby accidents either from that date. That Welsh bas.... er
    chief constable, Brumstrom, I think his name is, said it was hard
    telling parents they cannot have a camera near the school until their
    kid and three others have been mown down. Fair enough, but he will
    also have to tell parents their child was the first to be hit because
    the newly camouflaged camera did not remind the driver he was nearing
    an accident blackspot. Two different ways of looking at it.
    It does not matter to me why the driver slows down near the school
    zone: it is equally effective in saving life to slow down for the
    camera as it is to slow for the "school" sign. Two objects saying "slow
    down" are better than one.

    Oxfordshire, your area: the very place that prompted me to get the
    camera database: I was flashed at 36MPH on an open straight
    countrified road, in bright sunshine, on a wide traffic free road, with
    no visible dangers. The sort of road that is normally signed at 50mph
    or at national limits. I was driving conservatively slowly, at a very
    safe speed, but Thames Valley Police decided to hit me with 60 quid and
    3 points. The same week a copper killed a girl in Oxford, travelling
    at 70 at night in town, and was found not guilty of dangerous driving
    because he had a blue light flashing.
    I fought and won! But it made me realise that speed cameras are often
    sited and set to entrap motorists who are driving at perfectly safe
    speeds. One size fits all approach. I wanted to be able to continue to
    drive safely in the prevailing conditions, but without having the worry
    of knowing my exact speed, and without the need to watch out for
    cameras and to constantly check the speedo. So I bought the SatNav.
    I do not use it to enable me to speed between cameras, just to make
    the driving experience less paranoid, and to allow me to match my speed
    with the actual conditions.
    I finish with a quote from the TVP area:

    "Another ambulance driver doing his job has been the victim of police
    speed camera fanaticism. Lee Schramm recieved a fixed penalty notice
    for doing just 36mph in a 30mph zone whilst rushing two organs for
    transplant. He was driving a marked car with blue flashing lights, yet
    Thames Valley Police have apparently refused to scrap his fine and
    points. The Sun has described the police as "Speed Prats".

    The issue here, is that whilst visible cameras provide an incentive to
    drive legally at one single point, non-visible cameras would provide an
    incentive to drive legally all the time, cos you wouldn't know where
    they were. If they combined this with moving them around regularly,
    then the idiots who can't drive well would get their licences taken
    away from them.

    I think speed cameras are great. They only catch idiots who aren't
    paying enough attention to the road to even spot a speed limit sign. Or
    dumbasses who suppose that because there are 'no visible dangers' there
    aren't any dangers that they haven't noticed, despite admitting to
    being incapable of paying attention to the speed of their vehicle
    whilst driving. The double magic of them is that they pay for
    themselves, so don't cost anything to run, meaning that there's more
    money for traffic policing and other road safety initiatives.

    If you're not skilled enough, or have too poor eyesight to be able to
    see the signs at the side of the road that tell you how fast you should
    be going, you're a [censored] driver and shouldn't be allowed to drive, you
    shouldn't be investing in technological gimmicks to allow you to drive
    poorly.

  12. Wow, thanks for all the input.

    It has made me think - I already have Tom Tom Navagator on my PDA with
    one of those new Sirf III thingy recievers (and it is much better than
    the one I had before). I have hesitated to take my PDA on uni rides cos
    it is hugely useful in my life and it would seem too much of a risk of
    breaking it. Having said that, if there was a way I could adapt what I
    have now to uni riding for a fraction of the price I guess I would be
    interested. Any ideas?

    Maybe what you want is a rugged case eg.
    http://tinyurl.com/rgtt3
    http://tinyurl.com/emr45

    Dunno how this'd affect fitting the GPS though, unless your PDA is
    bluetooth. I'd be surprised if the cases don't have room, cos so much
    of the sort of work rugged PDAs are being used for involves location
    awareness.

    The big issue with using gps for unicycle route following (as opposed
    to just seeing your route at home), is that it's hard to have it
    somewhere you can see when riding, I think the wrist mounted ones may
    kind of fix this, cos you've got them out all the time. On a bike you
    mount it on the bars and follow an arrow on the screen, so it's easy.

    But, if you're using a PDA and you're a programmer or know one, it
    might be possible to write something that took a track file and talked
    to tell you which way to go, in the same way that the road navigation
    stuff does. Writing code that accesses the GPS isn't hard. There might
    be something for PDAs that does this already.

    If you could work out some way to be able to follow the GPS while
    riding, there are loads of routes available to download on the
    internet, loads of people use this as a way to follow new mountain
    biking routes.

    My eTrex Vista can be set to 34 different co-ordinate types. If the
    same holds for your Summit you don't -need- above type. Otherwise,
    there must be a tool (other than the GPS receiver itself, I mean some
    software or so) to convert between them. Some conversions can be done
    easily in Excel.

    I've got a small utility programme called Grid Inquest which converts
    between UK / N Ireland / Eire coordinate systems (OSGB36 and variants
    plus UTM) and WGS84 in both directions. Download from www.qgsl.com
    There are lots of similar programmes around. For the UK streetmap.co.uk
    has a coordinate conversion utility to/from OSGB to WGS84.

    poorly.

    Joe

    The expected reply: There is always at least one.
    JoeMarshall, do you drive? Are you an experienced driver? Do you
    ALWAYS stick to the speed limits: honestly! ...in traffic flowing at
    35 in a 30 zone, which it often does. Do you stick at 28 and annoy
    everyone behind you? An annoyed driver may well do something stupid,
    not all can remain calm. Maybe they should not be driving, but our
    driving test does not assess temperament. And when the traffic is
    flowing freely at 35mph, 90% of drivers are then driving to the
    conditions rather than the signs: are they all idiots? Indeed not.
    They are the majority and they are driving safely. The few who hold
    people up at 28 mph are *often* old drivers, some of whom should no
    longer be driving, too old and infirm to react appropriately when
    something happens. I see many of them. Rita, my next door neighbour:
    82 years old , still unable to reverse out of her drive without several
    goes at it, and does 28 mph everywhere. Buys a new car every time hers
    gets dented. A Godsend to the local Ford dealer. She will never get a
    speeding ticket, but she should not be in a driving seat either.
    Driving within the limit does not make you a safe driver. Driving
    sensibly and with thought does.

    The point is that speed limits, as signed, are somewhat arbitrary, and
    based around a number of factors: are there houses? street lamps?
    etc etc. One size fits all. They take no account of conditions on the
    day, and little account of many other relevant factors. So what is a
    reasonable limit in a howling night blizzard can be inappropriate at
    almost any other time. It works both ways around too: I have seen many
    drivers doing 70 or more in the outside lane of the M6, when I and 90%
    of other drivers had stopped because very, very heavy rain had made
    driving dangerous at ANY speed. A simple demonstration that a camera
    cannot house good sense in its box. A policeman would have had a chance
    to book them for dangerous driving, although in those conditions, had I
    been a copper, then I too would have been stopped on the hard
    shoulder.
    The multiples of 10mph on speed signs also restrict accurate
    evaluation. A road may be accurately considered safe at 37 mph: so is
    it then signed at 40 or at 30? If 40 then any driver doing 38 to 40
    is driving dangerously but legally? If 30 then any driver doing 31
    to 37 could be booked whilst driving safely? To drive "precisely to
    the speed signs" is like writing without any adjectives and adverbs. It
    is robotic. It has been shown that drivers trying to keep at a steady
    28-30 can get so bored that they make mistakes. They have had their
    brains replaced by the signs, and are not using their minds actively to
    drive sensibly. Some of them are a positive danger as they clockwatch
    their way down the road. At weekend, many of the speed signs near
    Leek were obscured by snow stuck to their faces: it didn't matter: I
    continued to drive at a safe speed, and reached my destination incident
    free.
    I would rather watch the road and drive safely than spend my time
    reading and remembering the profusion of roadside litterature (
    intentional misspelling!) that I am presented with on our roads these
    days.
    Yes I bought a SATNAV for guidance, and yes I added a camera database,
    so that I do not get booked for driving safely in a zone where someone
    else has got the sums wrong, or applied an arbitrary formula.
    And the vast amounts of money some new cameras take in day 1 of their
    existance, suggests to me that the speed limit at that camera is signed
    too low. Most drivers drive sensibly. A few don't.
    The police also need the support of the public, when I was booked for
    driving IMHO very safely at 36MPH, I felt a great sense of injustice.
    It was hard not to feel antagonistic towards the police. So I went out
    to beat the ticket, and I won and was proved right. I am not an
    "idiot" but merely someone who chooses to drive safely using my mind
    rather than driving precisely as directed by roadside lollipops. You
    would not be scared in my passenger seats.

  19. Wow Nao - re the speed camera thing.

    I have sat nav. I don't have the camera database installed.

    I believe in theory that everyone should stick to the speed limit, as
    in my experience people have proved time and again that they are not
    sensible/thoughtful. However, I do speed when going to work. (It's a
    long way and 95% of the time I have to do a certain stretch of 60mph at
    40. I have no idea why people always drive at this speed on this
    stretch of the road.)

    I do feel, however that people shouldn't be 'criminalised' for
    speeding.

    Back in Somerset there was a lot of evidence that the speed limits were
    set by who shouted the loudest. The road through the village of
    Somerton is NSL even though it is twisty, has high walls and trees on
    both sides to restrict visibility and houses fronting right on to the
    road; but at the other extreme just a mile up the road there is a 30
    limit along a long, straight section bordered by low hedges and fields
    with a few houses all set way back from the road. You can't help wonder
    whether any of the occupants of those properties have anything to do
    with the decision making process.
