“...the Karens there will RAT YOU OUT.”
Indeed! One of them ratted us out in California. We had one of our two Idaho-registered cars there for about six months. We got a letter from the CA Highway Patrol quoting the law saying you have to register the car in 30 days of moving a car into CA (I think - it might have been 21 days) AND that somebody had reported us!
Wow! 6 months in California is IMPRESSIVE!!! In Texas, car registration is so cheap that no one cares where you register your car.
But in Seattle, where people will have to plug-in and then unplug their cars in the 35 degree rain for 6 months every year, probably twice a week, they’ll get pissed seeing their neighbor not having to do any of that crap.
