For me it seems one of the most dangerous and aggressive acts not keeping the safety distance depending on the speed. A very simple rule seems to be absolutely unknown here: The “2-seconds rule”. When the car in front of you passes a significant point (e.g. light mast) just count in your mind “21-22″ (2 seconds). Your distance is safe as long as you do not pass the same point before you finished counting. But I have seen – whenever you keep that distance, other cars will fill this safety hole or even cars behind you will start showing aggressive behavior. One of the reasons might be wrong information giving in the driving schools, one teacher actually said that the distance is sufficient when you can see the back wheels of the car in front of you… What a defiance if simple Physics!!
I couldn’t agree more with you, Jens.
It would be interested to check in the accident reports, the number of crashes that happened in the simple configuration with one car bumping into the one in front.
Without any experience in “accidentology” my wild guess would be an easy 30%.
I drove a friend’s car the other day and found out that once the cruise control was on, if the car in front brakes, a sensor commands the braking of the car in the same proportion.
Technologically speaking it is not difficult to instal this kind of system onto EVERY car with maybe not with a braking function but the same annoying noise when you don’t have your seat belt to inform the driver that there is less than 2 seconds between the car in front.
And as for the speed cameras, if governments REALLY wanted to address the issue of road safety instead of money, they would place some devices to measure this interval between cars and whoever would be below would be fined.
They would make a lot more money that way and am sure it would have a better effect that fining for speeding.
