>>charging a battery while driving with an internal combustion engine

You understand how they work? The battery charging is from regenerative braking - capturing energy that otherwise would have been discarded as heat from friction braking.

You also understand that North America is a BIG place? We have the same chicken-and-egg problem of EVs and charging stations as the rest of the world but there's a LOT more territory to cover with charging stations. We're not there yet. For here, an appropriate vehicle might be a plug-in hybrid so day-to-day driving is electrified (which BTW that study was about but you failed to mention).

All that said, for anywhere the charging stations are reasonably close together but particularly the Cantons where the elec source is hydro, it makes no sense for a government to pay a subsidy. But taking that and claiming that it applies to the rest of the world is, well, the nicest way I can put it is 'poorly conceived'.
