Hybrids don’t support fast charging, and need to be plugged in way more frequently to stay on the electric powertrain (regen is only a small incremental improvement and not a power source itself, so a hybrid not charged is just a gas-powered car).

Hybrids only make sense when you can charge at home. Otherwise it’s better to get a BEV with 10x larger battery, that needs to be plugged in 10 times less often.

If they can't plug in at home or at work, why would they consider paying extra for a plug-in hybrid?

Try living in an apartment in a small town a good drive from a city. I dream everyday of a pure BEV, but the range and charging infrastructure are just not there. Oh and winters and hot summers exist.
