Then there are the hygeiene and “gaseous anomolies” issues when one goes to pick up on of those ‘share cars’ to ride around in, where one of the previous occupants has left a rather aromatic colon discharged reminder of the 3 bean tofu breakfast burrito he or she had that morning.
Those things can happen with one’s own family, too!
What a disgusting thought. I guess you never ride on airplanes, either, or go to public areas?
