We once had an Oldsmobile with vent windows - manual without cranks - and footwell vents.My '61 Impala must have been light years ahead of your Accord, a technological marvel! Not only did it have crank operated vent windows (manual turning the window and latching it is for poor people), it also had cable operated vents for the footwell... I get more air in that thing with everything opened up than I do in the '01 325Ci convertible we have with the top down.
They worked great as long as the car was moving.
While on vacation one summer, we got stuck in a traffic jam for over an hour on a brutally hot day.
The next year my Dad bought a new Buick with air conditioning.
