But motorcycling is a luxury activity. I was thinking about this on Sunday's ride. One comment I made was "why get a second motorcycle, just get a convertible and go on trips". But in thinking about it, part of the enjoyment of the trip is the preparation and the ride. I can't see taking the truck or car to Devil's Tower. You're in a box until you get there, stop, see the Tower, and go home. Meh. But riding the bike gets you into the environment. Experiencing the fog, the rain showers, the cooler weather, the smells!.
I suspect that even every car is autonomous, there will be a market for entertainment type vehicles. Boats, planes, motorcycles.
I read a story a few years back where teleportation was discovered and the story's father figured that with such an ease of travel, that all modes of transportation would be dropped. So he sold off all his stock in motorcycle companies. But there was a resurgence and increase in folks who ride motorcycles because it was a pleasure activity and not a necessity for getting to work or buying groceries.
So no, I don't think motorcycling will be impacted.
