They put one in front of my friend's house. It's a big plastic one almost as big as a speed table. The complainer Karens drive .03mph over it and get honked at or driven around. The trucks and vans, anything driven by an employee or a teenager just speeds right over and a small number of people go for air time. 11/10. Highly entertaining. And this is all in addition to having to listen to every vehicle accelerate after it of course.
