I own a Tesla with FSD. It’s actually surprisingly competent at highway driving. City streets, despite some people’s hot takes, are pretty decent if a route is heavily traveled (in the most recent versions they are mapping spaces using data collected from cars running the beta). The fun truly begins when you are trying to get off the interstate to visit a charger - these are actually some of the hardest spaces to solve since a lot of normal road design rules don’t get used here, and I’ve learned to just drive these bits manually.

Realistically, they can probably pull this off if they spend some time mapping their specific route in advance so that navigation errors don’t happen. They would likely time the trip so they enter the NYC area at night to keep traffic as easy as possible.

But make no mistake - it’s going to be years before you or I could hop in the car in Fremont and do nothing until we arrive in Times Square.
