Same thing happened to me! The tracks are just the right size to catch a skinny tire. They’re tricky to deal with. I thought I was being safe until the moment I had to swerve to avoid a car. My wheel caught in the track and I went flying. My arm and leg got all scratched up but somehow I didn’t break an arm. Those tracks are a menace and should be covered until when/if the city ever gets a trolley.
