Let me guess you also wash your car with dawn dish soap and dry it with an old bath towel.

New trucks. You see so many 50ish yo men driving brand new shiny 80-100k trucks that will never see even a 2x4 in the bed.

There’s not 0 risk. Setting a bag of trash or anything on your car is a good way to scratch it. Lots of micro scratches are what makes paint look terrible over time. I would never set anything on a car I actually care about.

Because 90% of people couldn’t care less about a car because it’s just an appliance to them.
