A HUGE safety feature in my neck of the woods is creating those horizontal ridges in the centerline of two lane roads. A guy who I can only assume was texting crossed that line headed right toward me a couple months ago and you could tell that hitting those grooves is what got him to turn back into his lane.
Without those grooves, his trajectory would have made it almost impossible to avoid him completely.
I have had quite a few close calls myself. Had a bad accident almost 10 years ago, breaking my pelvis in five places. But no car was involved. Just me, the bike and a poorly sited dumpster. :)
What gets me is the number of cyclists you see who are booming along with earbuds firmly in place and pretty much bolivious (as my daughter used to say) to what is going on around them.
Getting that distracted in a car is dangerous. Doing so on a bike is very nearly suicidal, IMO.
