The hardware changes to bring things like adaptive cruise control and automatic emergency braking to the bike would amount to just a few hundred dollars difference in cost, according to Dr. Karl Viktor Schaller, head of development for BMW Motorrad. Further, Dr. Schaller assured Roadshow that these technologies were only a few years away -- meaning more than 2, less than 10 -- and that when they did debut, it would be on the R-series touring bikes first. 

BMW sees the inclusion of advanced rider-aid systems as mandatory in a future where autonomous vehicles are the norm. While the tech wouldn't ride the bike for the rider, it could be used to help teach novice riders how to be safer on their new motorcycles, and it could also be used as a riding coach to help advanced riders come closer to the limits of their high-performance racing machine.
