Reic Posted May 22, 2009 Share Posted May 22, 2009 understand the general concept and it's popular usage, but you cannot measure distance with units of time. i was taught using car lengths... equally vague, of course. i've never heard of the well known rule of 3 seconds though. but if 3 seconds is safe, isn't 10 seconds even safer, let alone the primo safety afforded by 20 seconds?still a dumb question. lol, I have been told the car length thing too. 10 seconds is really really safe Link to comment Share on other sites More sharing options...
