      The recommendation changed from car lengths to seconds decades ago, but wasn’t well communicated fwict. I learned car lengths from my dad and then seconds when I got my motorcycle endorsement.

      If everyone were leaving 2 seconds of space, it also reduces stop and go traffic that is caused, or at least exacerbated, by the traffic wave phenomenon. But that’s even less well socialized.
