How can you avoid dangerous spills from catching the streetcar tracks with your bike?
You ride in the track on purpose. And to do that, you need training wheels.
I think Grist exaggerates the dangers of this silly move a little since streetcars generally move at less than bike speed.
It looks like a goofy fun experiment, and I’m sure these riders have figured out it’s a little bit limiting. What happens when you want to pass the train? And what’s to keep you from riding between the tracks anyway?
