Maybe you're just richer than the average person, that affluence buys you a lot of convenience that others can't access.

It's easy to forget the budget issues faced by many families when you're not facing that constantly yourself, but it's basically an existential consideration for a not insignificant proportion of the population.

You're circa $1700/year more expensive in fuel with your minivan[1] than with a comparably sized EV.

Your 5 hour / 300 mile journey takes around 30 mins more in the EV end to end (time spent stationary at a charger somewhere near the mid point of your route). Equiv of driving at 55mph average vs 60mph average over that time. I'd happily use the time to drink a flask of tea i brought with me and then go for a comfort break.

[1] assuming $4.80/gallon in a 25mpg minivan, vs an inefficient EV that only averages around 2mi/kwh at $0.30/kwh. Obv the 1700 excludes servicing, tyres and depreciation
