When I started teaching (5-6 years ago) I had many students from all walks of life coming out for training. I had pilots putting them in their planes to get to town from rural airports, and sailors putting them into their boats to use when then they landed in ports in the Caribbean.
Then wheels got faster and gear-wearing got intense and the demographics changed from everyday people to, I'll say, adventure riders. And we lost the regular folk, who generally see a geared up dude riding at speed and think, "yeah, looks cool, but not for me".
That said, functional things will almost find a way into the market and wheels are amazingly functional, easily the most efficient and practical way to get around for trips 10kms or less.
We'll get there, we just have to wait a bit for more casual riders to come back into the market.
