[net.auto] Learn to live with 55 MPH

[Honest Officer... I didn't take it off, it just fell off!]

How 'bout this one, All cars built with a little device that won't
allow the car to go > 55? Or better yet, have speed limit signs
that put out a signal that your car reads and won't allow you to go
any faster than. Of course devices like that could be easily
removed, or someone could set up a transmitter near the road to make
cars go 100, or .....

In Japan they require vehicles to carry a set of lights wired to a speed
detector.  This applies at least to trucks and busses; I'm not sure about
cars.  The device is apparently tamper-proof and causes three lights on
the cab to light up to indicate the speed.  In particular, the center
light comes on if the vehicle is speeding.  The lights on either side
come on at lower speeds.

I have actually seen vehicles travelling down the highway with the center
light flickering, thus advertising "Look!  I'm speeding!"

Well, I think trucks in Europe (at least in some countries) have to be
equipped with a "tachograph", which records the vehicle speed at all times,
and the record from the tachograph can be used to retroactively prove
speeding.  Trouble is, what if your speedometer is off (speedometers have
to read values >= the correct value, by law, at least in new cars)?  What
if you have to pass somebody noodling along at 50 on a 55MPH highway, and
you want to get past them reasonably quickly?  Cars in Japan have to have
chimes that sound when the car goes above some speed (I think 62MPH - 100KPH -
which is, I believe, the national speed limit), and a fuel cut-off device
that goes off at 100MPH or so.  I think that a cutoff flat at 55 would
be a major nuisance even for drivers who go 55 - and does nothing about
roads with lower speed limits.  The speed limit signs with transmitters
would be rather expensive and a major pain when they break down.  And
given the complaints about the 55MPH limit now, just imagine what'd happen
if something like this were *proposed*, much less *implemented*!
