I've lived in Las Vegas for 30 yrs and shortly or their after the move the population was small as the city started getting to get big so the city started putting up cameras on the stop lights and the public started asking what they were for, they said to help with the flow of traffic, as of today I don't think it has never been the case, I know they get a higher gas tax from the public so it can pay for roads school etc. As to date we always paid high gas from the rest of the nation, I think it's so the city can get more money from us, they say it to improve the roads, I've seen a lot of the same roads repaired over and over as they can't repair it right the first time, the people that lay pipes , electrical etc. For houses, apartment and other business tear up the roads and a crap job and no from the city looks at their Quailty of work, so what I'm saying here I have to set at these intersections around town so I can burn up more gas so the city has more of the gas tax to spend on wasted items
Thank you
For ur time
