Ha, so we have a new version of "Slug Bug" for those boring road trips. Rules are the same, first person that spots a Tesla gets to "Zap Tesla" someone. It isn't an arm punch like "Slug Bug", it is more a 5-finger poke and explosion for the zap. False zaps allow a return double zap. The things you do with 11-year old kids.
That game is deeply ingrained from a ton of road trips as a kid, I still want to reach over and tap whoever I'm with if I see a VW Beetle. Nowadays, I'm probably a bit more likely to see a Tesla in town, than a bug. Still pretty rare here, but they do pop up now and then, and now I have a way to let my wife know if I spot one. I'm sure she'll be very grateful you posted this.
