Pretty sure you’d maximise the fire hazard. You’d need a gas tank. Those contribute massively to fires in parking garages. Batteries do not contribute in those fires as Norway found out in the Sola parking garage fire. Not a single EV battery pack ignited. You’d have more chance of oil/gas leaks than with pure EVs. With hybrid you maximise the number of parts and things that can go wrong. With a small battery you maximise the number of charge cycles it experiences, so after 10-15 years you’d have both the issues with an old ICE and badly degraded battery. Not that I wouldn’t want to see small and smart series hybrid cars. At least in a transition period. There’s these linear free piston engines that could be very efficient for this. But a pure BEV is the ideal solution in the end.
