~~~~~~~~~~~~~~~~~~ agreed! some folks think that "maintaining" a vehicle means that you have to get some gas when the needle sticks on "E". Only those people who regularly think about oil, coolant, battery condition, etc. are helped by tire pressure warnings, because the others will say "gee, the car drives okay"............and don't even know where the oil dipstick is, or how to read it. Or if they do, they'll look at it and say "I guess that BLACK stuff is the oil!"
