If you're into that sort of thing, looking for the potential for bad, then road cycling is a wet dream.... IMHO....
IMHO, that depends 100% on the road. I have to ride a little over 5 miles round trip to and from the trail. All on residential streets with a top speed limit of 30 mph and marked bike lanes with plenty of room for cars to pass. ANd a ron of bike riders.
That may not fit your definition or road cycling but it's about as far as I'll push my luck.
