The solution to cellphone laws is pretty simple. Take 20% of the cops you use for speed enforcement and have them write tickets for failure to use a turn signal and obstructing traffic, as well as for jabbering/texting.
I would have said it is because those are harder to prove, but not if they have cop cams
And I am 100% convinced that they are setting up traffic lights to encourage speeding so they can write you a ticket. Around here, if you go the speed limit (or even a mph or two over) you seem to hit EVERY SINGLE red light. It can take you 15 minutes to go a couple miles down the road. But if you go about 10-15mph over the speed limit, you hit green lights 90% of the time. I've tried this out in many cities all around the Southwest and it works every time.
And at least some cops have control of at least some traffic lights. I think I already told this story here, but I sat at a red light for quite a long time with a cop behind me. It was almost if he was going to wait all night until I decided the light was broken, go through the light and then give me a ticket. When I didn't, he put on his lights anyway and asked where I was in a hurry (or something like that). From what I recall, he then finally let the light turn green and then pulled me over for "looking like" I was in a hurry.
I blame it on DST
