    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.

    Cathy

    Hi Cath, yes, as you have seen, I can become quite animated over
    cameras, although I don't universally detest them (**1). The probable
    reason most drive at 60 on your road is that it is a natural speed, one
    that people feel safe driving at, whilst on that stretch. I would guess
    you feel safe doing so too. And yes, time and time again a *few*
    drivers will prove they are not sensible. The inexperienced and the
    young will also make all too frequent errors of judgement. One thing
    that annoys me is that the fines/points will be applied regardless of
    past record, no lenient magistrates as for the first time vandal, the
    first time burglar or mugger. No one to quote your previous
    unblemished record.
    A friend had 38 years driving without so much as a parking fine, no
    accidents, nothing. He was flashed at 36 in a 30 zone. No
    compassion, no consideration of his clean record by the police. I
    donned my amateur barrister hat and got him off the hook in the
    magistrates court. It was fun! I believe that for such first
    offences, or for a small excess over the limit (say up to 40 in a 30 )
    there should be a system of stroppy warning letters first, recognising
    that factors such as I mentioned in the earlier post do exist. Thus
    treating the motorist in a similar way to other offenders.
    It is hard not to see cameras as cash raising machines, when, as
    reported in news just yesterday, one camera took 22,000+ pounds in just
    4 hours. In round figures at that rate it would have totalled a
    million pounds in a week. One "idiot" every 36 seconds?.....or was the
    area perhaps signed badly or inappropriately?

    BBC: "A single speed camera caught nearly 400 speeders in just four
    hours, clocking up more than £5,000 an hour in fines."

    **1: there is *ONE* camera I detest. I sometimes stay with friends:
    some of you may even know them : John and Zyllan: both ride unicycles.
    They have a GATSO camera outside their house which constantly flashes
    through their front bedroom window. I hate that one: really messes
    up my sleep when I stay.

  2. I do agree on some of your points. My next door neighbour got 'done' and
    has had to attend a 3 hour 'school' on the dangers of speeding. I think
    she was doing 35 in a 30 limit. 🙄

    Yet in some places I believe that the speed limit is not low enough.
    They show horrendous adverts of a 'kill your speed not a child' that
    show how much better it is to hit a child at 20mph than 30, yet streets
    where children play rarely have an official speed limit of 20mph.

  3. As this thread is now discussing UK speed limits I thought I’d just
    mention that a vehicles speedometer is typically only within 10%
    accurate. This means that, as I understand it, there is some leniency
    in speed cameras i.e. if the speed limit is 40mph then you should only
    get a ticket when your going 45mph and above. Of course you can’t just
    go 44mph and think you’ll be OK as your speedometer could be out by 10%
    and you’ll be doing more than 48mph. This has another side effect, you
    could be driving behind someone you think is going slower than the
    limit and they think they’re going faster than the limit yet you’re
    both going spot on the speed limit!

    From my experience when I use my GPS in my vehicle the speedometer
    always shows a lower speed (typically 10%) than the GPS which,
    according to Garmin, with a good signal ought to be accurate to about
    0.5mph.

    I’ve got a clean license and I’d like to keep it that way so I try to
    drive within the limits but most of all I try to drive safely. I do use
    my GPS with a camera database when I’m driving somewhere I don’t know
    so that I don’t make a mistake. Heck I spell correctly most of the time
    but I still use a spell checker!

    It might be worth getting it checked , cos they're supposed to only
    read up to 10% over the real speed, and never below the real speed. ie.
    It should never be possible to be flashed if your speedo says lower
    than the speed limit. Although to be honest it's probably more likely
    to be the GPS that's high, I believe our ones at work don't give very
    accurate current speed readings for some reason.

    Going back on topic, have you used your wrist mounted GPS for
    navigation on unknown routes as opposed to just seeing where you've
    been? Any idea how well they work for that?

    :eek: I wrote 'lower' when I meant 'higher' - I'll show you tomorrow.

    I have and it works really well as long as the map you prepare the
    route from is accurate...

    Bike mounted: 'Garmin Edge 305'
    (http://www.garmin.com/products/edge305/)

    This or the cheaper 205 are quite nice but aren't quite the kind of
    thing I want in a GPS; the screen is rather tiny and it seems to have
    loads of "training" functions that I don't really care about. If they
    make a version of the eTrex with this new chip in it they will probably
    get my money, but until then I shall remain unconvinced.

    That is unusual: most car speedos read over the actual road speed
    rather than under. At true (GPS) 70mph my car registers 77 on the
    dial.

    Your drive clean policy seemes very much in touch with my own.

    I read a book " Relativity Made Simple."
    And simple it was, as long as you could follow easy mathematical
    concepts such as:

    A=B, B=C, therefore A=D.

  11. Just noticed a pair of new Garmin GPS with SiRFIII: 'GPS Map 60C'
    (http://www.garmin.com/products/gpsmap60csx/) and 'GPS Map 76C'
    (http://www.garmin.com/products/gpsmap76cx/)- might be worth looking
    at...but they're expensive and US-only...Then again, water-proof and
    they float...very nice.

  12. My usual pattern with gadget buying is that I have a little look around
    for what I think will meet my needs and is not so expensive. Then I use
    it, decide which feature I like and don't like and what extra features
    I would like and use it until I get fed up with the features I don't
    like, or christmas comes or something and then I buy a more expensive
    one which is exactly what I want and then I use it til it wears out or
    (more likely) someone releases an even more super dooper model that I
    have to have.

    Yes the better recievers sound better. And floating - fantastic. Just
    US - a bit of a problem. I was looking at the garmin 60xc originally.
    Now I would love colour and a bit of fanciness but at the moment I'm a
    bit low on the cash. Roll on christmas.

  13. Hurrah, new toy has arrived.
    In my initial burst of enthusaism and learning about things GPS, I was
    wondering if anyone had any waypoint data bases or data bases of routes
    for good off road unicyling?
