5 year EV owner, would never buy ICE again, but things in theory & in practice do not always match. Road trip can have a broad definition. My parents live 75 miles away. When you do visit your parents? Holidays.. aka winter. So the nominal 310mi Tesla should make a 150mi round trip no problem right? Well.. ermm. I've had trips where my battery was at 80%, cold soaked, snowing, a bit of wind.. but highway flow of traffic was 75mph. What should have been a routine half-battery using trip required me to top off on the way home as not to land too close to zero in freezing weather.
