It is amazing to me that there are not more crashes around here in Washington State. We have got plenty of view obstructing hills, but that is not the problem.
The bad drivers who are not smoking pot are playing with their cell phones and a lot of those who are smoking or "vaping" pot are also playing with their cell phones. And by playing with their cell phones, I do not mean that they are merely talking on them. They are looking down at their phones while they are texting or trying to get the phone to do something. The other day I even saw some guy with a laptop in the passenger's seat and he was doing something with that while driving.
You can tell who they are even when you can't see what they are up to because of tinted windows. One minute they will be leaving an excessive amount of following distance or driving 10 mph below the speed limit. The next thing you know they are doing 20 mph over the speed limit weaving in and out of traffic and passing on the right even when there is plenty of space to pass on the left. Then they will start driving slow again.
My new Jeep has a dashboard screen with icons to adjust various functions. It's great for the backup camera and when stopped to visualize settings, but not so when driving.
