seriously? I get it, drivers in general are not cautious enough of pedestrians and cyclists. but if a 16-wheeler is following so closely that the other driver is at risk of getting rear-ended when they stop, the pedestrian is probably toast anyway. the semi is just going to push the car straight through the pedestrian. now instead of one person dead there's 10 tons of mass careening through the street out of control, putting a lot more lives at risk.
