to be fair, the check engine light is usually attached to the environmental-emissions controls, which can be very expensive to fix, more expensive than the car is worth. so unless there is some other symptom, a lot of people drive with the check engine light on. even having a loose gas cap will set off the light. not that I'm advocating ignoring the light, just saying i understand why so many people do

Agree! Or maybe driving around at high speeds with your brake lines leaking.
