Depends on the gas prices, but yeah, even in the US often ‘fast chargers’ would be equivalent or even more expensive than gas.
If you take fast chargers with the milage most EVs get (roughly 2mi/kwh), the per kwh price needs to be roughly $0.35/kwh or lower for electric to be cheaper (home rates essentially across the US are lower than this), but fast chargers often climb to $0.45-0.55/kwh.
Umm, there are no EVs you should be going 75mph for hours at a time in unless you want to trash your range.
Not sure if you have ever actually driven an EV, but typically in my 300mi range vehicle, I usually stop every 200 miles, roughly every 3 hours for charging, stop for 20 minutes and am back on my way. Sure, am I often a little slow than if I had gas? Yes, but that’s ok, I also always arrive in my EV refreshed, have eaten, and not wore out.
