Cyclists in Riga, Latvia donned homemade contraptions made of bamboo and twine to simulate the amount of space a vehicle takes up on the road. Cycling advocate Viesturs Silenieks came up with the idea as a way to raise awareness for International Car Free Day (Sept. 22).

With the help of local cycling group Divrintenis, the team took to the streets on a rainy day during morning rush hour traffic. Be sure to check out the video and additional photos below.
