I don’t know if there is an actual term for this move, but I’ve only ever seen Illinois people do this so I’ve taken to calling it The Illinois Left. What happens is at a stop light there will be cars going straight both directions, the offender is first in line in the left turn lane. When the light turns green they gun it making a left in front of on coming traffic who is also beginning to move forward. Like, you saved 30 seconds, congrats.
And just so you Illinois peoples don’t forgot
