It has been code since forever to install a hood vent over a gas stove. "But people might not use it so we should consider restricting use of gas stoves" is no different to "people might not use seatbelts so we should consider not letting them drive cars".
I don't know that it's common knowledge to turn on the vent fan every time you light the burner, like it is that you should buckle your seatbelt. Do you turn it on when you boil water? I don't, but I guess I should. I never thought about it until now.
It might indeed be overblown, but I think it's worth looking into. I'm not saying it should be banned though.
Also what is the alternative to driving a car that's reasonable for most people? Can't catch a bus or a train in the sticks.
