I would be shocked by this, but I recently read an article about the rise of cell phone use by people riding bicycles in the Netherlands. It was written by an E R doc. It seems there has been a rise in the amount of bicyclists running into each other and fixed objects such as light polls and other assorted polls, planters, corner store fronts etc. Even though the parked car chaser didn't mention cell phone use, being drunk, drugged up, crazy or any combination of what I listed. This could be another case of cellphoneitus.
