We all care for our cars and are distressed when any warning light comes on. We want it fixed asap.
There's a lot of other car owner's that see cars as a transport necessity. As long as they get from point A to B, they are content. They ignore warning lights as long as the car still gets them where they are going. Or they never heard of run flats. "The tyres look OK, the light must be faulty". Or they conveniently use faulty logic to avoid any inconvenience. "That light is for regular tyres. I have run flats so it's OK to keep driving indefinitely."
