Jaywalking is enforced with an iron fist in Las Vegas. Yes, I agree it's dumb most of the time, but it's part of the culture here. You'll be cited by police in the hospital if you're hit by a vehicle while jaywalking.
Since I grew up in Boston, I was used to crossing when the road was clear regardless of the status on the walk / don't walk indicator. I did it here a few times at first and it sent oncoming traffic barreling to a halt while I waited in the median. Folks assume if you're jaywalking you're "all in" and going for it.
Where I lived in CA, a car entering a crosswalk with a person in it got a ticket. Set one foot off the curb, everybody stopped. Look like you might step off the curb, folks stopped. But that was some time ago; these things change.
