ELI5: Why stunt people don't use air bags in car stunts?

I just watched a couple of car stunts they don't seem to use any. What is the reason?

The collision sensors for airbags are to sensitive and they would deploy when the car lands a jump or gets a bump.  They cost a fortune to replace when they DO go off, and if the stunt man is properly restrained they don't add any value in the event of a crash.  In addition, airbags hurt quite a lot when they are deployed.  Less than going through the wind shield, but more than you might think.
