One car that I had when I was stationed in Germany lost its reverse gear and I drove it for a couple of months like that

When I drive the SUV with the trailer attached I really don’t have reverse because I cannot, for the life of me, back it up. Makes for some interesting trips. And there are a couple of really nice men out there who have gotten me back in the right direction.
My brother had that, too. You learn quickly what things you can't do. Forgot late one night and parked it nose against a fence, slightly downhill. Got some other drunks to push him out.
One of my buddies had a stick shift car with no starter, so he had to look for downhill parking spaces. Roll and pop the clutch!
