500 mile range is a requirement before I buy an EV. From what I’ve seen, batteries shouldn’t regularly be charged beyond 80% which takes range down to 400 miles and that’s with perfect conditions. Cold weather probably takes range down to around 300. Also, have you noticed how fast traffic moves on rural interstates? Speeds are 75 mph and higher which will quickly sap range. Even with higher ranges you still have the issue of slow charging compared to filling a gas tank in 5 minutes or less.
