This car cut me off within about a foot of my bumper, as I was driving along through the intersection at Main Street and Third Street in Longmont. 

First, this driver made an illegal lane change (in an intersection) and nearly took the front of my car off.  Finally, no turn signal was given.

Cars regularly sneak into this 'middle' lane at this intersection, as the right lane is 'right turn only' and the left lane is 'left turn only.' 

I'm getting tired of people barging their way in to try and get one or two cars ahead, causing a dangerous driving condition.
