Does anyone else hold onto the “Oh Shit Handle” when riding in the car as a passenger?

I am conducting research for a Psychology Grad School project and am wondering if anyone else holds onto the “Oh Shit Handle” when riding in the car as a passenger?

If you do, do you hold it for the entire ride, at random times or more on turns, stops and curvy/bumpy roads? If you don’t, do you have a specific reason why you don’t?

Thank you for your help and responses in advance!
