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 is not wasteful. Energy is not a scarce thing in the universe.

Using energy is not bad. Creating excess carbon emissions is bad.

We need to be able to hold two ideas in our heads instead of blindly repeating trendy religious dogma.

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).
