This looks like everyday driving in New England 😀
Yeah, you seem to be going fast on some of the urban streets.
Also, for number two. When turning left onto a four-lane road, you should stay in the left lane and signal into the right lane.

In this case, had there been a collision that would be irrelevant. He was already in the right lane and the individual in the left lane changed from the left lane to the right.
This does look like everyday driving ... let us know when you got a crash!
