Even when cyclists have their own lanes, they need to cross the streetcar tracks in order to (1) make turns and (2) avoid obstacles (e.g. cars suddenly pulling out). If they don't plan and execute the track crossing at a perpendicular enough angle, the wheel gets trapped and the rider usually wipes out. The victim is then often blamed for getting hurt by infrastructure of a design that is known to hurt people [0].

You're absolutely right. I think the way Amsterdam does this is instructive: nearly all cycling-trolley crossings are completely perpendicular, and all cycling-automotive crossings are isolated and separate from any nearby trolley crossing.
