When I visit a friend, it is very convenient to be able to charge my phone without having my own charger with me and just use theirs. At the same time, I park my car and don't care to look for compatible parking space. As for tires, I don't even know nor care what sizes they are but I'm glad the air pistons are the same across all makers/brands/sizes so I don't worry I have to go to the right fuel station to check my air pressure. Right?
