Meanwhile, fairly common cycling parameters lead to well under 10 Wh/km at comfortable cruising speeds, and with things like velomobiles you kinda start around 5 Wh/km, and 3 Wh/km is possible without significantly compromising the practicality of the vehicle.

Sure, sure, lower speeds, lower cargo capacity, lower safety, &c. &c.

But it’s still a useful comparison to contemplate, especially when considering the nascent category Lightweight Electric Vehicles, which in its most interesting form isn’t far off “ebike minus pedals”. Cars are still pretty power-inefficient as a general concept.
