It’s situational but electric may not be a bad option for some delivery routes. Our guy stops at each mailbox along the curb shutting the engine off each time. I always imagined they go through starters and batteries like crazy. Of course I don’t really know what’s involved with EV maintenance..
The primary maintenance items among the Tesla owners that I know are new tires and windshield wiper fluid.
You probably couldn’t come up with a vehicle fleet more ideally suited to EVs than the USPS delivery trucks. The routes are not particularly long and the trucks return to the barn every night. No range anxiety.
I was following the bidding for the new USPS delivery truck and I was really surprised when an EV wasn’t chosen. Oshkosh, who got the contract, primarily builds military vehicles which makes me wonder if political connection played a big role in the award.
