It's not going as fast as the tesla. iirc the wind resistance goes up as the square of the speed (I need to find a ref for this, I read it all the time, I guess https://en.wikipedia.org/wiki/Drag_equation https://en.wikipedia.org/wiki/Drag_equation). Anyway, you can't compare a bike going much slower than a vehicle. If we were riding bikes, at much lower speeds than 70, then no doubt we'd be getting vastly more distance for energy used. But that's a separate argument from the impact of weight on energy usage.

They’re both vehicles that can take you from point a to point b, so they can be compared.

  That's true they they are both vehicles that move you, but a bike vs a car are in very different classes, unless your car only goes 30 mph in normal use, like in a congested city.
