Are you nuts about letting people drive your manual trans car?

My mom has driven my vette to church, I don’t see what the big deal is. I’ve let a bunch of my friends drive my vette. Most of the time I’m with them in the car, but I have let my good friends take it to go race people or get ice cream. I beat the car pretty good, so I don’t mind if they do. Plus I know they know that if they break it they will help fix it.
