NYC, for example, outlawed car alarms years ago, as it was a complete nuisance. Some are still grandfathered and some are probably illegally installed. I hear them sometimes, but it's pretty rare.
When I was younger and lived in Jamaica (Queens), there was this particular TALKING car alarm that was very touchy and drove me up the wall.
They may have banned after-market alarms, but factory-installed car alarms are standard on pretty much every new car in the past 10+ years anyway. I still hear those go off on occasion in NYC.
