Have you ever considered how few truckers it would take to blockade all the interstates into and out of a major city? If they were angry enough to disable their trucks, those highways would stay closed for a long time. I hope the Ctrl-Left does not push them that far.
Just disabling the GPS on the semis alone would cause total loss of control for the truck owners, and any ones who did bust through blockades have those persnickety things called ‘tires’.
I already have a plan for dead vehicle choked roads. Not going to post it here but the problem has a relatively fast, simple solution.
