Looks like there will be a vehicle (manned of course) following the trucks at this time (the same way oversized cargo/load moves today).

Unlike "the way oversized cargo/load moves today," the chase vehicle is just another Peterbilt truck pulling cargo, but with a safety driver. It's not a flag car or something like that.

That can't be the long term plan for self-driving trucks?
