Road racing down, but has never been that big in the US. High school mtn bike race is big, road race is practically non-existent.
Road riding- cruising along among the older set, and the also among the young-and-fast. Pretty good rural roads in my area. Sheer number of cyclists seems to have overwhelmed the ability of the yahoos to honk and yell- they have largely given up.
Bike culture and transportation riding- booming. Gridlock breeds alternatives to driving cars.
Mtn biking- popular, but suffers from limited available trails. A mtn bike is much more likely to be $$$$ than a road bike IME.
Gravel: All the cool kids are on it. Good and in many areas abundant resource.
Cost generally- sure there are expensive bikes, but still doesn't come close the the overall cost of many other sports/activities.
Risk- Overpopulation of cars is doing away with expectations of being able to go fast, and improving cycling infrastructure both
moderate danger. We are on the way to becoming a third world country, so cycling should become more dense.
