Not only impractical, but of dubious utility. Race car drivers
wear 5-point harnesses, full-face helmets, and neck restraints.
What is the airbag going to protect them from? An airbag in
a passenger car is intended to keep your head from impacting
hard parts of the car, and to some extent from your chest
hitting the steering wheel, but all that is already being prevented
by the other safety measures in race cars. Race drivers pretty
routinely survive crashes at speeds well over 100 MPH.

If everyone in a passenger car was belted in and wearing a helmet,
there would be no need for airbags in them either.
