I personally wouldn’t stop to help anybody, which is unfortunate. Most people have cellphones and have cellphone chargers in their cars, so they can get help if they need it.
If perchance the situation looks serious, I’d probably be inclined to call the local police to look into it. It’s just too chancy today to do that.
One day in Seattle I was in a not busy industrial area when I saw parked on the side of the road a big older truck that a box behind the cab - the kind with a roll up door. The engine hood was up and a guy was standing by the the open back door of the truck holding battery cables and he waved them at me. I got out of there as fast as I could. I could have just seen myself being thrown into the back of that truck.
Come to think of it wonder why he was at the back of the truck next to that open door when if his battery was dead he would have needed to hook the cables to the engine at the front of the truck. Hmmm
Maybe it was nothing..but maybe not.
I stop for bikers.
That’s about it.
