Car registration/insurance

I moved here 10 years ago, tbh I was pulled over a couple times in just a week “hands free state” just moving here I used my phones gps ALL THE TIME!! I wasn’t bothered just had to pickup a phone mount. Then like my 3 rd week was pulled over a few time for my out of state tags, well we were still going back and forth to our home state. Changed them the next month. Totally understood. There again was never upset with the officers, just explained our circumstance and all this good. Now though I see cars with even tags, expired registrations and I’m not talking about months but literally years!!! My neighbors moved here 3 years ago from Texas. Never has registered in Nevada or Texas. Doesn’t even have a registration sticker. They’re not the only ones!!! Just driving to work (a 20 minute commute) you see so many ppl on their phones and no tags!! I’m sure if they have no tags I’m sure they have no insurance!!! Why has it became so laxed???? Let’s not get started with all the jaywalking or the beggars walking right down the middle of the streets!! WHY??? One last complaint.. why are ppl allowed to park in the handicap parking without permission??? Is that not code enforcement??
