Transferring 2700 megajoules of energy to an f150 via gasoline in a few minutes is very convenient, something that would take a Tesla a few hours. If consumers were concerned with efficiency the same way engineers were, we'd all be driving electric hummers and cybertrucks.
There are 2 types of convenience.
- Being able to fuel up quickly on a long trip
- Having your fuel tank full at the beginning of every single trip.
Hydrogen fuel cells (and combustion engines in general) are better only for the former case. Since most people drive less than 300 miles most of the time, it's hard to argue a car optimized for longer trips is more convenient for most drivers.
