I don't know what it is about Teslas, but everytime my wife and I get in one, we start feeling carsick after a while. It's only with Teslas too.
Still, as much as I'd never buy a Tesla, it is a functional car for the most part, and worst case you turn on the hazards and pull over (if the car doesn't actively try to kill you). A brain implant sounds like an absurdly horrible idea. What's the best outcome of one of these anyway? Ads playing in your thoughts?
