Peds and cats are the most random creatures on the road. Cats don't have as good of lawyers...
Usually a siren/horn works well enough on the peds around here, cars for the most part are deaf or the typical northeastern indifferent. Generally however they will not intently hit a well lit rider who is using the lane. Edgers on the other hand get picked off more frequently, though admittedly neither has presented fairly high numbers. Right hooks are very common, especially around the schools in the morning(go fig).
