Since 90% of accidents are caused by people who tailgate and drive way too close to be able to stop safely (source: totally made up by me, but the number must be pretty high), it seems like it would be an interesting, useful, and probably not to hard to do option to have an alert on the dash when you are following someone too close...
v1: Simply based on your speed, the expected stopping distance on a normal dry road with good tires, and the distance to the car ahead, have a little alert show up that says "slow down, following distance too close for safe stopping".
v2: adding in knowledge of the car and whats going on around you, is the road probably wet? (has it rained in the past hour, based on weather service reports), how old are your tires? are you going uphill or downhill?
v3: adding in knowledge of other traffic around you, is the car ahead of you following too closely, is the car behind you following too closely? is there a traffic jam ahead? (based on traffic data) is it a car or truck ahead of you *based on radar / video analysis)
Even if you cant fix the idiot behind you who is tailgating (until we get those built in machine guns I've been wanting for a while), if you have enough room ahead of you when the car ahead does a panic stop, you can decelerate slowly enough to hope he doesn't hit you stop as well before hitting anyone.
I will admit that I sometimes follow too closely when I am not paying enough attention, while I admit that the hardcore drivers out there who like driving at the edge would probably never listen to it anyway, something like this would help highlight it for me, and make me back off when it comes up.
so, thoughts? or am I behind the times and someone has already done this? (I don't have my car yet, but didn't see it in the manual), or just stupid and no one would ever listen to it anyway?
