    following your logic and description of motorway use getting off the motorway would be a piece of cake

    If you are in the outside lane you are moving faster than the lane to your left so are in a perfect position to move into a gap between two cars, same for moving into the inside lane.

    Just like it works now in fact, it's called anticipation :) - unless of course you drive a BMW/Audi where you drive along in the outside lane until 200 metres from the junction then dive across all three lanes :)

    Yes, but because cars would probably be driving closer together there would be less "gaps" to drop into.

    ah so we have gone from assuming that voluntary system would be compulsory, that every one would abide by the rules you described and that they would all drive nose to tail.

    Sorry, that's a lot of assumptions all in one example to rubbish an experimental system we know very little about :)

    Perhaps we could also assume that cars may also have a "two second" gap between them and the car in front automatically created by the same (or future generation) system - surely that would solve the problems in your example?

    We could always fit them with compulsory Distronic as well.:D

    A little help please!

    I have long felt that the motorist has been placed at at a disadvantage with regard to his ability to comply with the increasing demands made on him as an individual to obey traffic laws. :eek: The traps for the unwary are manifold especially when on roads he is unfamiliar with. Most motorists want to obey the law, not because they like it but because they wish to avoid the fiscal and social consequences of breaking it.:( Witness one posters plight to be on his last warning before losing his licence.:crazy: While the "AUTHORITIES" have doppler shift radar, digital speed cameras, speed averaging cameras and processing, automatic numberplate recognition, CCTV lane monitoring and computerised vehicle registration databases the motorist driving the average mid range saloon or family MPV is given a speedometer costing £10 as an aid to complying with all these legislative demands.:mad: I grant you that on high end cars such as Mercedes the owner can opt for cruise control and satellite navigation but even that often comes at a considerable additional cost.:( So "in principle" I am in favour of any system which "helps" a driver to obey the law since its about time some technology was implemented on the drivers side. :bannana: IMHO many motoring offences are committed involuntarily by drivers who in the main try to obey the law within reason as best they can.:eek:

    We already have a model showing what happens with speed limiters fitted to vehicles, IE Trucks & Coaches, they have very accurate Tachometers and speed limiters fitted, yet the speed of each individual vehicle is slightly different resulting in very slow overtaking, it is very very very frustrating sitting behind a vehicle going 2 or 3 miles an hour slower than you when you have to drive large distances every day so the result is they take up two lanes overtaking for mile after mile, as it goes there is more tail gating now than there ever was before limiters and contrary to some peoples beliefs it does not make for a more relaxing experience for any road user, coach drivers are the same, restricted to 65 MPH and not allowed into the outside lane on a 3 or more lane motorway, so get stuck behind trucks, and generally have to live in the center lane. I think they should only be fitted to vehicles driven by drivers who have proved themselves incapable of obeying the law on receiving their licence back after a ban for speed related reasons.
    Leave the rest alone.


    I don't know if this counts:crazy:

    I can recall that close tailgating by trucks was commonplace before speed limiters.

    There are more bigger trucks now.

    The solution to the 'overtaking problem' for HGVs is to calibrate the speed limiters so there is no practical variation. Then specify a minimum separation between vehicles. There is still an issue with regard to overtaking on hills where vehicles may not be able to maintain regulated speed.

    That sounds like just about every motorway I travel on, except they aren't maintaining 70mph in the outside lane, more like 65.

    My assumption (possibly incorrect) is that this would be a function of full throttle acceleration and doesn't require a 'button' at all.

    It wouldn't make any difference whether the car is auto or manual when the pedal is fully mashed you receive full power. Our cars currently do this, including switching off the air-con and canceling the speed limiter, so it's definitely possible.

    Of course a driver might try driving 'mashed' but if anyone has actually tried that, it's not sustainable and rather frightening.

    I think GPS capping of cars is dangerous, and flania1's example is good enough for me as an example of why speed above the speed limit may be needed. I also think it is an intrusion into our lives if such a system was capped.

    How many folk here have overtaken a car on an A road that was going say 45mph and maybe for the sake of doing the manouver safely have strayed above the speed limit, not by much but still quantifiably above it and doing so was safer than doing the manouver completely in the bounds of the law.

    The Japanese have a more effective system, limits in cars capped @ 112mph IIRC. There is no reason on a public road why a device like this would ever invade upon a drivers control unless they were driving (well like me) well above and intentionally above the speed limit. It also pleases the "anti big brother brigade" which well, is me and a significant amount of others (where is recycled when you need him)
