Protected bike lanes in the US are far too often built in ways that increase risk. In Austin, I basically refuse to use the two most significant protected bike lanes near where I live and work because drivers far too frequently turn into the lanes at intersections without looking. The city put signs up telling drivers to look and yield at some intersections, but the signs don't seem to have had any effect other than covering the ass of the city. Well built infrastructure would be preferred. But ultimately we need more than just infrastructure. Drivers need to change their dangerous behavior too.
