The advantage of straight EV or advanced hybrids that they need only
to handle cruise, as peak comes from spike cache. Plus, regenerative
braking, smaller gear to no gears (hub motor, can be done with low
unsprung mass), advanced control with power electronics driven by
software, drive by wire, including ability to integrate powerful
computers for future autonomous navigation, and so on.
As soon as sufficiently reliable batteries get sufficiently cheap
the ICE is effectively finished, at least for commute and short
cruises. Current stock diesel cars do >1000 km on a single tank,
no way to do that with even advanced unobtainium batteries unless
in flimsy ultralites.
