Airbags are not forbidden in aircraft. They just haven’t been considered to offer enough safety benfit for their weight and cost in most cases. That is starting to change though, and airbags integrated into aircraft seatbelts are becoming more common. They can be found in first class in a number of commercial aircraft, and are sold to be retrofitted into private planes.
America can’t have 4-wheeled road-legal flying cars. 4-wheeled road legal cars must have airbags, but airbags are forbidden in aircraft.
EDIT: I stand corrected.

There are many reasons I doubt this car will make it into commercial production, but the airbags will be OK.
TIL. I was regurgitating what I saw in a video a while back about the Switchblade, which was supposedly 3 wheeled because of the airbag thing.
Easy, just eject them when you take off, and inject them when you land.
