20 minutes every 2 - 3 hours of rare long distance driving is acceptable, considering I save 4 hours of petrol station visits per yer vs my old diesel. Not to mention the fuel cost savings.
Oh I'm not referring to road trips here, they've been mostly fine in my EV. The issue is for people without a garage or a readily accessible charger then can use. My brother lives in Brighton, MA, and to charge his car he'd need to go out of his way to find a CCS charger and then sit there for 40 minutes about once a week. It just removes an EV as an option unless he moves elsewhere.
Depends how fast your car charges. 2017 Model S 75D charges for 30-40m every ~90 minutes of driving.
It's not as bad as it sounds, or I'm lying to myself, but having the 90 minute planned stops makes a cross country trip seem a lot closer ... even though it's doing the opposite.
