>You’ll be able to put more cars faster and closer together when they’re autonomous. I hate this misconception about driving. That being closer together (assuming front to back) is somehow useful. That restricts lateral movement and is one of the biggest causes of slowdowns on freeways. Say you're in the fast lane and you need to exit. If there is a column of cars next to myou, driving less than 1 car space apart, all of those cars need to slow down to adjust and let you over (or you need to slow down significantly, slowing the column of cars in your lane until you find an opening). Leaving space allows for lateral movement with no adjustment of speed.
