What was something incredibly stupid you did when you were younger that you regret?

In my early 20's I had zero issue getting into a car where someone drunk was behind the wheel. I used to drive absolutely smashed myself and am shocked I never got pulled over or caused any grief. There was one incident I remember getting into the car with my best mate to go pick up pizza. Mind you prior to leaving we had been drinking a lot and I was alright for the most part but he admitted he couldn't see where he was going while driving. I thought nothing of it and felt relaxed but thinking back I should have been very concerned and probably should have drove or just had the damn thing delivered.

For the record I do want to state I no longer drive around absolutely plastered. I am no longer a binge drinker like I once was mainly because my upper abdomen began to hurt when I drank so I had to slow down. That combined with anxiety attacks from drinking has really made me quit just about.
