I knew that.
My point was no one should wait for an idiot light to tell them to periodically check the tire pressure or the level of the oil on their dipstick -- if you are picking up a new car or a used car check you should inspect it when you get it home to make sure everything is correct before you start racking up the miles.
Those are simple checks, and I'd also recommend you check your lugnuts if you have someone else rotating your tires (or removing the wheels to inspect your brakes, etc) and check the dipstick if you have someone else doing your oil changes to make sure there is oil in the car and the oil isn't dissapearing.
Nobody else is really going to care about your car that much (at least not as much as you should).
