Besides the horrible traffic, EVERY day, you will have to be on the lookout for:
1. Taxis - Stopping wherever the hell they want to, mostly at intersections, in the middle of the road, then just wait for about 5 minutes so that they can grab passengers.
2. Golden Arrow buses, they are on par with the taxi drivers IMO, disregard rules of the road, and basically don't give a continental if you are next to them, they WILL change from the far left lane to the far right lane so that they can get onto Montague Drive, no matter what or who is in their way.
3. Idiotic Pedestrians, who think that the bridge walk way is there just for show. A number of pedestrians get hit every morning and afternoon on Bosmansdam.
4. 18 wheelers and other trucks - see Golden Arrow buses above.
I for one avoid Bosmansdam like the plague.
