I guess you are underestimating just how terrible internal combustion engines are and overestimating charging + driving losses.
Consider that hybrids or HEVs can improve substantially on the efficiency of just a pure ICE. I guess the problem with using an ICE for driving directly is that you are often forced to run it at RPMs and states where it is nowhere near that hypothetical 30% efficiency, simply to get the acceleration the user demands.
