I use the one second of space per ten miles and hour of speed. So at 65, you should have six and a half seconds between you and the next car.
I was taught in Driver's Ed that you always keep 2 seconds between you, no matter the speed. The 2 seconds are measured by: when the guy in front of you passes an object, you should be able to count 2 seconds before YOU pass it. The length of space increases naturally and perfectly as you speed up.

How are you measuring 6 seconds, TG?

same method. I only know that below three seconds of reaction time is dangerous. I can't remember the program, but they had a truck full of huge foam blocks. They had drivers follow it the way they would normally. then they kicked off the blocks. people closer than three seconds usually ended up creating a huge explosion of styrofoam.

I do know that I've had traffic come to a complete stop, and with the timing I give myself, I've ended up a foot or two off of the bumper of a car that was well ahead of me. and all of the intervening time was used up while braking heavily.
