Did auto manufacturers stop putting tunr signals on cars??

I was driving down the I-15, one of the major highways that gets you around the Las Vegas Valley, to pick Kelly up at the airport last night, and given the increased traffic due to the holiday weekend I was not suprised at how busy the roadway wass, I was blown away by something else: It seems like No one (except me) was using their turn signals. A four lane highway (plus on/offramps) loaded to the limit with cars that were just changing lanes and exiting/entering the highway with no indication of their intent. If there is one thing I make sure I do that was in the handbook, it's use my signals.. I want you to know that I am turning, so you won;t hit me.... THere was a bad accident at Sahara, no doubt the result of someone not using their signals.... I exited and saw a lot of flashing yellow arrows, road work at Las Vegas BLVD and Sahara on Memorial day, must have been emergency work, Yet another headache caused by non-signal users???? as the signs indicated, I got over two lanes to the left and the lane I was in was clear, except that now all of the people who had their heads up their arses were then coming over into this lane with no signal, so back to bumper-to-bumper for a bit. How hard is is to look ahead when you are driving, and to follow the instructions that are posted, a lot of our taxes go towards those fancy orange and yellow signs....As I was getting closer to the intersection, and the cones were closing off the other lanes completely, a guy in a white Jeep Grand Cherokee starts to come into my lane, nearly making contact, and not flashing a signal or anything. My window was open, his window was open, so I yelled " If you had your turn signal on I would have stopped for you, but if you think you can just come over, forget it" or somehting like that... blows me away, and the airport is no different. Let me set up the scenario for you, driving up to passenger pickup, there are a LOT of people on the right side of the road, and a few on the left, so how many times did I get cutt of by people suddenly realizing that they needed to pull over to my lane to pick up their family?? Three, one of which used his/her signal.. thank you sir/ma'am in the Lexus Why Bother SUV...

Just a rant.

That and I'm still waiting to hear when my upright bass will be delivered, arrrrrrghhhhh!
