I hear ya man. It also depends, at least in my experience what kind of car you drive as well. When I had my Regal with the quiet tame V6, people always screwed with me on the road. Cutting me off, not letting me pass (not that I could with that whopping 110 hp, felt more like 80), and just in general being douches. Then when I got my Thunderbird (pictured) NO ONE was within 10 yards of me at any time. It was awesome. If someone did piss me off, I popped it in neutral and let it go pop. The carb was so jacked up if you got on it and let off immediately it would backfire out the exhaust, which by the way was disconnected at the manifolds on both sides due to broken studs so it was basically running open manifolds for the entire time I had it, and it would sound like someone shooting a 22 at you. That got em out of the way for sure. I really miss that car. It was a hoot and a half to drive. Never left me stranded and ran great.
I think people in general, by nature, are just plum stupid. Not to toot my own horn, but I think I'm a pretty damn good driver. I know how to control my car in various weather conditions, I know what to do, what not to do, etc. They should have IQ tests as well as vision and all the other tests to drive. Just because you can memorize the answers like a highschool History test doesn't mean you should be allowed to pilot anything more than a 50cc moped.
Everyone nowadays are in their own little world, texting, tweeting, snappchatting 24/7. Some of them are insane enough to do it while driving. If everyone outright banned the usage of mobile devices while driving, and made it fineable (I think California has this already) there would be less accidents, and less stupidity all around. All this coming from an 18 year old. It's sickening. The other day I saw this fairly attractive woman, mid 20s to early 30s, with THREE kids in the back of her SUV and she was just textin away without a care in the world doing 30mph. Jesus.
