Ignoring environmental and supply issues, the physics advantage of ICE cars is 1) half the reaction mass is atmospheric oxygen, so doesn't count against vehicle weight, 2) the weight being propelled goes down as you burn fuel vs carrying around dead battery.

The downside is 3/4 of ICE energy is waste heat, not propulsion, vs 90% of battery energy going to motion, not heat. (I don't care about charging and transmission loss, that doesn't affect range for weight.)
