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

I’m conducting research for a Grad School Psychology project and am wondering if you hold onto the “Oh Shit Handle” when riding in the car?

If so, do you hold onto 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 for why you don’t?
