This is Walkbump, a soft fist-shaped crosswalk button designed by Alfredo Adán that you fist-bump to push. Or you can do what I do and push it with your butt because you don't want to get your hands dirty. I live in a bad area where I guarantee less than 5% of people wash their hands after going to the bathroom, and the majority of the population is going to the bathroom in alleyways and behind dumpsters. You ever heard of Skid Row? Well imagine that times fifty. I can't even leave my apartment without....actually, I just can't leave my apartment period.
Keep going for another shot and a short video of the thing in action.
