Does that bike lane go next to parked cars? You can imagine that even conscientious drivers could fail to see a bike approaching that fast and open their door into its path.
I admit I rode my bike up to 35-45 MPH sometimes in my youth, just with pedaling and gravity. But, I was wise enough to realize I belong in a normal traffic lane at that point, not flying along the edge near pedestrians, parked cars, etc. And I wasn't exceeding the posted speed limit for that road.
I had a less wise friend, with a very aerodynamic road bike, who hit ~60 MPH (in a 25 MPH zone) and T-boned a car because they did not consider unsafe it was with the limited sight lines. I felt sorry for the driver who, by all accounts, didn't do anything wrong.
