Bangladesh uses gridded speed bumps specifically designed to slow down bicycles and three-wheeled rickshaws, which constitute a large portion of traffic, by interfering with their wheel movement, while allowing cars to pass more easily by crossing at an angle or adjusting their path.

These Speed Bumps Are Designed for Rickshaws Not Cars!本站添加:
Why does Bangladesh use speed bumps that look different from the rest of the world?
They're not actually made for cars.
Since bicycles and three-wheeled rickshaws make up a large part of the traffic, these gridded barriers are designed to slow them down or restrict access by interfering with wheel movement.
Cars, however, can often pass more easily by crossing at an angle or adjusting their path.
