You expect all of that from the public? The public that forgets to renew their license and registration, get the car inspected, CHECK THE AIR PRESSURE IN THEIR TIRES! Because no one checks their tires anymore the government mandated that cars must now have monitoring so the car will warn you that you are an idiot driving on a flat tire! The last time anyone looked at their tires was to wash them. Now you don't have to change your tire anymore, new cars don't have spares! Nobody remembers to change their oil regularly. I see cars all the time that are leased and the oil was NEVER changed. Most owners don't know how to open their hoods and if they did they would mess things up. About twice a year I see cars where the owner poured windshield washer fluid into the brake system. Why you ask? The message center kept flashing a warning, low fluid. Most owners of older cars DO want to know how to take care of their car and are willing to learn and get their hands dirty, not the general public who will buy a new car and drive it from gas station to gas station never doing anything.
