Yeah, I try not to block crosswalks if it looks like anyone will be using it, but partially into the crosswalk often feels like the safest place to be while waiting for a light.

We get those bike "boxes" - the first spot right next to the lights, that is reserved for cyclists - and they help a lot.

In London we have those but cars frequently stop over them either because the drivers are ignorant of the rules, they don’t care or they were too ambitious about making a green and ended up being forced to stop at the last minute. So as a cyclist I frequently have to push up to the pedestrian crossing for my own safety from cars behind.

The "dedicated" bike lane that cars are merging into to turn right?

No right turn or dedicated lights and they cyclists still do it. Quit making excuses

"They" = "some".
