I don’t know exactly, and I’m not an EV driver, but considering how many cars I see at supercharger stations, it seems to have a use case.

I’m guessing it’s an American thing too though, we can drive many more hours and no one is driving straight 4, let alone 5 hours going 75+ mph in an EV because no one is going to run their battery down to zero. On top of that Americans really don’t like taking long breaks on road trips because that only extends the trip that in a fuel vehicle can, well, could commonly be 6-20 hours driving in the past.

All the winning we are doing over here is quickly changing the mobility of American though. But that’s a whole different and interesting topic because it has major implications for America’s survival as a single entity that people overlook. America has held together to a large extent precisely because Americans could afford being mobile during the American century, i.e., the glue that kept the country together and made it feel like it belonged to us, an actual nation. That glue is breaking down for many reasons, one being expensive, impractical mobility.

Some Tesla owners still have free supercharging so they'll be there because it's free "fuel".

For your road trip example let's say we take a 1000 mile trip. With an EV that can be done in 6 legs (sandbagging it), maybe even 5 or 4 now. So that's 5 stops, over 16 or so hours of driving. If you average charge takes 30 minutes (sandbagging it) instead of 10, that adds 1 hour and 40 minutes or about 15% of total time. And this is pretty much worst case.

I would think that's perfectly acceptable, but that's just an opinion. It'll give you time to go to the bathroom, stretch your legs, have a bite etcetera. If you're going to be peeing in a bottle and eating while driving, yes you can do it in less time.

I would strongly suggest, the next time you do one of those trips. Time how long you actually spend at a stop, it might not be far off the 15 minute mark on average
