Do you own a BEV though?
At 70mph, your 300 mile range car is getting maybe 250-270, if it's 21C out. if it is colder or hotter, range does drop a bit to a lot. Dead of winter can get more like 150-175 miles range.
Then on top of it, for road trips, you often use the battery from 10-60.
Combine those two things, and your dead of winter BEV is needing to stop like every 100 miles.
But, thats like 5% of trips. most of the time this is vast overkill.
