Exactly, with EV's people are in cars more, which makes it harder to rob them, as it gives them time to call the police, possibly pull a weapon, etc. You are a lot more vulnerable when holding a gas pump handle to your car than sitting inside a locked vehicle.
Once there are more EV's, EV charging stations will be busier than gas stations, if for no other reason than the fact that it takes longer to fill up. I've been to gas stations in rural areas where there is nobody there at night, no other cars either, and the the lighting just puts makes you stick out like a sore thumb, as everything around the station is all dark.
My point was that EV charging stations are no more a target for crime than gas stations, perhaps less.
