    The gap you leave should be speed-dependent and about 2 seconds to allow for reaction time. Yes, this caps the highway’s capacity to 0.5 cars per second per lane but roads are inherently inefficient.

      Aye, and 2 seconds is the bare minimum. A company I have worked for wanted 4 seconds between you and the car in front. That always felt a little much, but it definitely helped prevent wrecks.

        In my state, it’s one car length(15-20 feet) for every 10mph. Good luck getting anyone to actually follow it though! Getting on a major highway here is like the Autobahn.

        2 seconds assumes an instantaneous reaction and perfect road conditions. In the EU they’ll teach you about 3s and at least +1 in poor conditions.

      3 seconds is the guideline I’ve been taught here in Sweden, but yeah. Riding too close is crazy dangerous and I don’t understand why people keep doing it.
