In all my years, driving an "uber", I never had anyone yak in my car. They did bleed all over, though.
I had a guy I had to pull out of the river, after he attempted to hide from us. I got him to agree to come out of the river, and he was caked with mud, from his waist down. I had a brand new cruiser at the time. I popped the trunk and "allowed" him to ride back there(trunk lid open of course). I didn't think about the speed bumps I had to go over and when I did, he moaned each time the lid came down and bopped him on the head. Only had to go about a mile, so I figured it was a good idea. Apparently the LT didn't see the rationale, and gave me a talkin to.
Good luck, Lee.
