few hundred miles IF you dont need to run A/C or heat.. then its cut in half. and what if theres no where to plug in when you get there ? bring 10 miles of extension cord? and why do people think its cost free ? the 240V electricity for up to 8 hours for recharge aint free. Batteries last maybe 4-5 yrs.. cost $10K for new ones!, And then theres the autonomous driving ones that get confused by any flashing light and crash into Fire Trucks, Ambulances, Road Construction signs .. I would never trust my life to a car computer to drive me 70 mph. This tech is NOT READY FOR PRIME TIME
