Because our society is spoiled, averse to consequences, and addicted to pleasure. People cannot tolerate it when they don't get what they want. What they want (when being pulled over) is NOT to go to jail, hence, due their conditioning, they avoid the consequence. Up to and including bringing injury and death onto themselves and strangers.
It's insane this is downvoted when it's the truth. Again and again the person is running from something small, but that's not an indictment of the chase, it's proof of how freaking stupid and self-centered the subject is: they are willing to put dozens of lives at risk to avoid something like getting their car towed because they're driving on a suspended license. The officer chases them because they don't know why they're running (but it must be a good reason to risk picking up a felony), not because going after a suspended license is worth a chase.
We are seeing the result of a combination of factors including aversion to consequences and the inability to empathize with those they put at risk.
its a breakdown of community, with capitalism largely to blame. In small towns, this type of behavior is less likely when you know the sheriff or judge and feel like they are a part of your social sphere. In a large city, any red-light-flashing cop is just an NPC that spawed and will take your in-game credits. I think this is the result - for many of us - when each person we see every day is likely someone we'll never see again. The megacity is just a huge machine with sharp gears and lurking dangers you have to evade.
