Oh, totally agree! I wasn't necessarily referring to electric cars specifically, more just comparing how much energy different things store, although it does highlight why building long-range and high-performance electric cars is a Hard Problem. There's a lot of things that are different. The 50L of fuel in my car is going to weigh about 45kg and will get me about 800km, and the batteries in a Tesla weigh 300-500kg (not sure exactly, found a few different numbers). But like you say, the power train is considerably different, etc etc.
