Telling people to watch the hot side pipes is a lot like a wet paint sign or don't touch sign. They will touch them for sure. I used to have a piece of insulation that rolled up and stored along side the seat and you just unrolled it when the door was open and it covered the pipe the full width of the door. I had snaps on it and when not using it I could take it off and put it in the trunk. This I put in just after a guy left his right hand on the side pipe. Never could get the lines of the palm of his hand where you couldn't see them in the sun.
