I rest my case. Who has the worst traffic? (Drivers)

Most of the stuff that happens around here is just plain stupid **** in traffic.
Like as everyone was stopping for a red light a woman in an Audi passed me and then jumped over between me and the car in front of me and then nailed her brakes to stop in the short little distance she jumped into, causing me to have to get on mine hard because she took up my stopping distance.
There wasn't anyone behind me, but noooo she had to pass someone first.

Driving a tractor trailer unit every day in an urban area, I get jackasses cutting in front of me constantly, and more often than not, there's no other traffic behind for a fair distance, makes no sense, they just gotta get there first. Have to laugh at those who speed past me and a block or two up the road I'm right beside them at the next traffic light.
