Vegas is well-known for this kind of thing (maybe Tabs can vouch). The nature and layout of the city is such that there are very large, wide roads with long stretches between lights. This creates an incentive for people to run the lights because they don't feel like braking from 50 or 60 mph to sit there FOREVER. I work out of Vegas sometimes for our firm (we have a satellite office there) and I was told this on Day #1 - "locals count 'one-one thousand, two-one thousand , three-one thousand' before moving once the light turns green" for exactly this reason.

Another issue is that because of the long stretches between lights (and probably exacerbated by the fact that half the city is drunk at any given time), it's very easy to get rear-ended at a light because the next driver humming along fat dumb and happy doesn't "see" you. They might see you, but it doesn't register. It's not what they expect or want to see, so they plow into you. My boss was sitting at a light and had the guy right next to him get plowed into by a pizza delivery guy in this manner doing about 45-50. That'll get your attention from 5 feet away. Guy was messed up pretty good too (wasn't wearing a seat belt).

Point is, when sitting at a light without anyone behind you - ALWAYS pay attention to who's coming up behind you - and how quickly. Whether in Vegas or elsewhere. I learned this riding motorcycles.
