:yawn: This will never be compulsory all the while the car is YOUR property - i can see it being done on company cars, hire cars etc but not when its yor own car and have the right to refuse entry to anyone.
Think of the cost to the DOT having to install this to every vehicle, who pays for repairs if they go faulty, manufactures won't want the cost added on and not exactly a selling point is it "yes sir 400bhp and a top speed of 70mph". What if for instance I go on the unlimited stretch of the German Autobahn ? I'm still limited to 70mph and in danger of being hit by a must faster car.
Still won't stop you doing 70 in a 30 zone though will it
and most accidents/deaths occur in built up zones and people speeding - never hear of pedestrians being knocked over on a motorway.
I want a device thats stops jaywalking and chav kids playing in the street.
