Is that "same direction travel divided between autonomous trucks and all other traffic"? Or "only on highways where traffic directions are separated by a median"?

The former sounds like a massive (understating it probably) infrastructure investment. Trains sound better (as other comment while I was typing notes).

The latter doesn't solve the issues noted in the recent article here: https://kevinchen.co/blog/autonomous-trucking-harder-than-ri...

Am curious to hear more thoughts/insights.
