250 miles is 402 km. It's well over 3 hours at highway speeds, which IMO is the limit for any reasonable day trip as a recharge while you're there means it's really 6+ hours per day of driving.
Granted, this assumes you can charge at that location, but EV charging stations are plentiful.
EV chargers exist in many areas, but fast chargers are much thinner on the ground.
So currently, you need to park by a non-fast-charger for 6+ hours at your destination if you want to consume your full range one way. And if all the chargers are in use/broken when you arrive, you’re pretty screwed. Broken is surprisingly common, there appears to be an agency problem with charger maintenance.
I was disappointed to realize this; I’m going to have to borrow a Prius to make my winter break 300 mile road trip. My wife just wasn’t interested in the adventure of searching for available, not currently broken chargers to get the extra 75 miles of range we’d need.
Tesla owners have a better experience in this regard.
I generally assume this is just growing pains, their are over 1/2 million Tesla model 3 reservations. The end point is going to be most parking spaces having a charging station operated at a slight profit. Or possibly even in road charging for absolutely unlimited range.
