@jeremyjudkins_ Far more than 5 min if including the time to go off the route to drive into a gas station. By the way, in NJ, you are not allowed to pump the gas yourself. “Professionals” are required (by law) do it for you and you have to tip them. Aug 7, 2023: New Jersey is now the last

@WholeMarsBlog The FUD from media since last November has been relentless. Started from “EV won’t work in cold”, then “EV won’t sell” (true for non-Tesla EV), then “FSD not safe”, then “Elon lies about FSD all the time”, then this “Every car maker has self driving”.
