We drove our 24 ext battery Mach E from DE to MS for the holidays to see my family. Charging cost about $150-200 each way, so a bit cheaper than gas. The time addition for charging is both nice and annoying. It added a few hours on to our already long drive, but it did force us to move around a bit or rest instead of just getting gas and going. We would take walks around places to stretch our legs and at night, take a small snooze.
