Driving is wasteful. Cybertrucks and Prius's use similar amounts of energy per mile. Cybertruck is 0.4-0.5 kWh/mile, the Prius is 0.6-0.7 kWh/mile.

Of course the Prius Prime on electricity is way more efficient than both, but it still uses a lot more energy than a house.

European units (`Energy/100km`) work nicely here, lots of EVs are around `20 kWh/100km`, and most residential housing around here consumes less than `20kWh/day`, actually averaging `20kWh/day` would probably cover a well insulated house including heating (heatpump).

Yes, driving, compared to living, uses ridiculous amounts of energy.

For comparison my cargo ebike, which is not particularly efficient, consumes about 30 Wh/mi (0.03kWh/mi) in medium assist while transporting an adult and two kids.

Are those numbers right? 0.4 kWh/mile is 24.85 kWh/100km compared to about 14 kWh/100km my Kia Niro EV uses.

Driving uses a lot of energy. It's wasteful if you aren't getting a good use out of it (of which just driving around to relax could me considered a good use, but of which some manager requiring RTO might not be).
