So this means that his brakes were inadequate, his transmission was
automatic and his ignition key was jammed? I don't think so!
I did wonder about the brake, yes, but I have no clue how these
automatic speed thingies work.
It says later in the article that he eventually managed to stop by
pulling out the electronic key card, which is presumaly the equivalent
of an ignition key.
Well, that's wrong, then. I recently drove a new Renault (hire car).
There is a positive electromagnetic lock which passes through a hole in
the card and physically prevents its removal while the engine is
running, so the journalist was writing bollocks. So what's new? When I
first read this story on a French news-site, the driver was quoted as
saying that he eventually stalled the engine by braking hard, but as
he'd previously said he'd tried to brake and it had had no effect on
the engine I'm not sure I believe this either.
But I understand the new Renaults are 'fly by wire' at least as far as
the accelerator pedal goes (so are many cars these days) so it isn't
inconceivable that a software fault would 'jam' the car at maximum
throttle. I would have expected the engine start/stop button still to
operate, though... but of course this is probably fly by wire too, and
if the computer had crashed it might not be paying attention.
Quoted message said:Quoted message said:As an aside, if Renault are fitting automatic speed regulators, why
aren't they limiting the maximum speed to the national speed limit?
Excellent question.
Indeed.
The one I was driving did have a significant - very noticeable - blip in
the throttle response curve at around 6200 revs which I assumed was
intended to tell you you were approaching the red line (6500 revs). I
didn't like this a bit! But if they can do that I don't see why they
can't put a similar blip into the curve as you pass the speed limit.
That way at least you couldn't pretend you didn't know you were
speeding.
