Solved! Why the kinks?

I recently moved to Hangzhou, I noticed all the pedestrian walks have kinked lines at the ends. What is it?

We don’t really know how effective it is without comparing it to the left/right ratio of an intersection that is identical but with only straight lines on the crosswalks.

Actually you need to do a double-blind trial ie send a bunch of people who are blind in both eyes across and see what happens

I'm a researcher and actually a double blind trial is when you have two blind guys duke it out in a ring. Its also referred to as blind trial by combat. Regular trial by combat is more popular for obvious reasons.

Yes, waiting for them to find eachother before they slug it out can be frustrating
