Considering what you save in fuel and maintenance EV's don't really cost more than comparable ICE's
I've had my ICE car for 4 years and not paid a cent for maintenance if you discount the fact that "free" maintenance was included in the purchase price. I've spent about $3000 in fuel in that time. The car is a paid for 2012 Passat V6, although I sort of wish I'd gotten the TDI.
Hell, you tell me where you're going, I can see what the current options are.
Los Angeles, CA to a bit past Roseburg, OR in 11 hours.
There is very little future in being right when your boss is wrong.
