I think too many people drive without common sense these days. They'll risk causing an accident to get ahead of 1, 2, 10 cars maybe. People are too fvcking stupid to realize you'll maybe save a few seconds maybe even a minute if you spend your whole commute acting like a NASCAR driver. Just because there is physically room to fit your car between two other cars doesn't mean you should do it; there is hardly any etiquette or consideration anymore. Why not just wait for a bigger gap to change lanes, why not let that guy in, why are you tailgating someone on an entrance ramp (do you even know what a zipper merge is), what is the big rush?
It seems like no one actually pays attention to driving anymore nor has the ability to see or analyze potential scenarios that will play out around them. Everything is a surprise! Gas it, slam on the brakes, gas it, race up to the light, gas it, cut that guy off, what is a blinker, why does everyone flip me off?
