> The general rule is one car length for every 10 mph

I really wish other cars on the highway observed this rule, but it’s common to see people doing ~80 mph with like two car lengths of buffer. When I myself maintain proper following distance, other drivers take this as an invitation to move into the empty space, forcing me further back in the cluster (and annoying the driver behind me).

Essentially the problem when one respects sensible security distances. Others just move in. Even when you want to roll faster on say a 2 lane motorway but can't without compromising that distance.
