Traffic lights. They serve a purpose, sure, but it's a terrible lie by municipalities to say the timing on them has anything to do with helping the flow of traffic. They are timed specifically to coax drivers into speeding.
A million times this!
How does that work?
Another pet peeve: people who can't STFU during a movie.
On most highways where they are used, in Jersey anyway, if you go about 10-15 above the limit, you will typically hit most green lights/be able to get through the yellow. If you drive right around the limit, expect to hit about every red. And you don't just hit the red... you will typically juuuuuusssttt miss getting through the yellow.
It's hard to explain, but there is incentive to speed in Jersey, and they ticket people left and right to raise funds for going 10 or so above the limit. It can get even worse late at night, where REALLY flying will almost always mean a straight shot down the highway w/out any stops at all.
I'm no conspiracy theorist, but I do see something diabolical behind traffic lights. Typically when its late and I can't see a cop or any other cars I just go through them. I get wonderful life out of my brakes... tell you that much.
