Ha! When I was a kid and we were living in Purdy’s/Somers (NY) my parents left my brother and I in the car while they ran into a market. Parking lot was on an incline. One of us (not sure who) jumped in the front seat and messed with something. You guessed it. The car rolled backwards, across 202 (busy road), and into the service station across the street. Same deal. No damage, no injuries, we thought it was a hoot. Could’ve ended much differently of course...
