I agree 150% that many people just are not paying attention. I can also understand the frustration if you have a long drive to and from work and travel up the road.
I myself have just adapated as well as I can. I drive fron Ridge to Piney Point and back, so for me driving on 235 in the California area is an experience these days.
I grew up in the city and spent a good amount of times on 8 lane roads and interstates. I prefer here all in all. I could make more money in my field of work if I were to travel but my sanity is worth so much more.
I keep one thing in mind. Late is late it doesn't matter if it's 10 seconds or twenty minutes.
P.S. I am the slow poke where I work since I will only drive 5-10 over the speed limit. So I wait until they all leave ahead of me at night.
