The first scenario is basically what happened with the convoys in DC a while back. Every day, they’d drive down, drive around a while, and then leave. I live in the DC area, but don’t drive in DC often, but from what I heard, the impact was minimal.
I don’t know how many trucks were involved, but I do know those trucks are expensive to buy and maintain, too expensive to keep running them in non-revenue service like that for long.
