Going from lane to lane in traffic... more specifically into the carpool lane.
When driving on the freeway and going in and out of the carpool lane to pass people. Usually bad drivers that are slowing down the flow of traffic.
I was spilling in traffic today because of the occasional slow driver in the fast lane.

I spill through traffic to get around bad drivers but stay in the carpool lane as little as possible to avoid a ticket.
