I don’t understand why they had to go with Tesla and Polestar. It’s not really the issue with EV ambition but because Teslas are expensive to fix. Plenty of other EVs out there.
There were no other EVs with a competitive charging network.
I rented an EV at hertz in Nashville recently. I ended up with a Model Y, but they had hyundai, Kias, Polestars, some Chevy Bolts all available for renting.
