Have you noticed people not pulling up to stoplights?

52. Here in Minnesota, there are two reasons:

First, nobody in Minnesota ever, ever makes a decent left turn from one road onto another. They ALL cut the corner, instead of making a good square turn. Truly. Nobody, but nobody makes a proper left turn here.

Second, many left turn lanes in the state actually have the induction vehicle detection coil where a second car in the lane will trigger it. How that works is that if there are two cars in the left turn lane, the left turn arrow will go green to let left turners go before through traffic. If there's only one car, it won't, and you'll have to wait until opposing traffic has a gap before turning left. If you stop so part of your car is over that induction loop, you'll get a green arrow and be able to make your turn ahead of the green light for through traffic.

They're very clever with that practice on busy arterial streets, and stopping back of the line will get you a green arrow.
