That's kind of a cartoony extreme extrapolation. Of course people should not be driving stupid fast, but people shouldn't be blocking traffic either.
It's really simple, don't cruise the left lane. If you are not passing stay right.
If the car in front of you is traveling slower than you want, check your mirrors to make sure someone is not currently passing you. Then signal, check again, and merge into the left lane to pass. Once you have safely passed, get out of the left lane. Keep right until you need to pass again.
Let law enforcement deal with the speeders. Do not make them weave left and right through traffic and mix some innocent driver in their recklessness.
I'm not going to change your mind, so I'm not going to continue going back and forth, but I will say that "cartoony extrapolation" is not any different than what I see on a daily basis during my 8 years as a professional driver.
The destruction that can be caused by flagrantly disobeying the posted speed limit is not worth the extra couple of minutes you *think* you are saving.
I'm speaking both from personal experience and statistics provided by both NYS and NYC, so before the "anecdotal evidence" police come to tear me down, I know what I'm talking about and don't feel the need to post links on TB.
