I’ve only ever owned 3 vehicles but even the cars I’ve borrowed or rented the feet heat always sucks it just blows it straight forward back into the engine rather than down at my feet, I always have to shove my feet directly up into the dash to get heat, is there a reason we can’t adjust the feet vent or any other solution?
I’d look at some electric cars, they often have very powerful heaters from the built-in heat pumps, love my 10-year-old Renault Zoe for that reason alone.
