It's no that they are busy eating doughnuts, thats a bullshit rarely punishable offense, its a felony leaving the scene assuming it occurs on a Hwy, County Road, or interstate or city street. Parking lots constitute private property, and many states have a no fault legislation for such places.
It's a suck ass deal, and I hate people who do it. The big problem is our society lacks any consideration or respect for other people and others property. If you want an education, go work for a county or city E-911 center, dispatch center, or go be a cop. Things are different once you see how things really are, most agencies are underfunded, undermanned and have so many calls per shift they rarely spend effort on a case that more than likely will be thrown out of court by a crafty defense attorney or shitty judge (we have a ton).
I can't tell you how many 911 calls I get on possibly drunk people, CNI drivers, or speeders on the interstate, when the county of a 100+ square miles has one two, sometimes 3 or 4 deputies on and your busy with wrecks, domestics, shootings, and EMS support you can't go 110 to catch every possible bad driver (I realize these are different situations, this is an example). Highway patrols are under similar circumstances and normally have very little 10-8 (free patrol roaming) time in a shift.
Even worse there are lots of people who crank 911, make false reports, and call in things incorrectly making it difficult to do much of anything sometimes. My suggestion is too be aggressivley cautious while driving, park away from vehicles in a parking lot, sure you may have to walk but whats a few extra steps compared to 1200+ dollars in body work. People need to bring back things like respect, consideration, and compassion if everyone of us tries to live a little better others may just catch on.
I am not trying to be a dick, but from my point of view I really wanted to share at least some of it with you, not for sympathy merely to enlighten you with a little "inside" knowledge.
Good luck
