Yes, there were a few times where I had to hit my brakes harder and faster than I would have liked to avoid the other people in front of me, and a couple of times when the people behind me had to do the same to avoid hitting me because of the "flow" (or lack thereof) of traffic created by these people... and there was no real way of getting around them - every time the road opened up a little bit, the next traffic light would turn and traffic would get all bunched up again... and there was one or two of these oblivious, dangerous, confused drivers in every single lane of traffic, stopping any lane from moving reasonably. Add to it that my vehicle has one of those double clutch transmissions and couldn't figure out what gear to be in most of the time... It was horrible. Every part of that stretch of road was "jerky"... I would have rather been sitting in a real traffic jam like you find in the cities...
I'm glad that your cousin got out of the charges and situation!!
