That was my thought. If I were caught unarmed in that situation I would proceed to keep driving until I found a cop. After all, if they damage the vehicle so badly that it can’t drive, what is the point?
Years ago Newark NJ had a spat of these “bump-and-rob” crimes; the police told people at the time to just drive to a police station (cell phones weren’t so common then). This type of crime isn’t new, though maybe it is to Baltimore. I guess this is what ferals have to do when everyone knows to stay the hell away from them - they have to search father afield for victims.
