Honestly surprised Honda hasn’t designed a hybrid that’s more generator and less hybrid but I suspect that has to do with air and noise pollution loopholes for generators versus engines.

Nah, the BMW i3 had one of these as an option, as does some Chinese car, with no regulatory difficulties. Also a common arrangement for ‘hybrid’ buses and trains.

The i3 certainly had some us regulatory difficulties, they had to change the battery and fuel tank sizes.
