Solid argument for outlawing fossil fuels.

Lol. Yep, and not to mention regenerative braking on EVs actually recoups and stores the energy as it slows the vehicle's descent!

Which you otherwise lose to friction and air resistance

This is also a problem for electric vehicles, just to a lesser extent.

Right. But let’s make sure there’s a replacement first.

Stopping distances are increased when travelling downhill, so likely more dangerous.
