People going slow on the merge lane then having to slow down for them to merge because they wanted to wait until the end of the merge lane to merge

When there is a right only lane with its own traffic signal and the arrow is green but some how ppl ignore that and look at the red light next to it when that light is for the lane next to them
Also I almost hit a cyclist today.
I didn't know the were allowed to go the opposite direction in the bike lane. I was turning right and didn't bother looking that way since I wasn't expecting anything
