When I was a young roadie, we would ride through the mountains and sometimes be paced by a friend on a moped. I thought it was just our unique way of training. Until today. Youtube is fantastic for new discoveries. Little did I know about such a thing as dernies. It's more than just for training. They actually race with these things in front of them. I still don't know how the races work. But for those interested, here's a couple of representative youtubes of dernies.
