I believe the law of unanticipated consequences will bite us on the fanny when it comes to autonomous vehicles.
Already Mchelien is marketing special tires for self-driving cars since those cars do not recognize, nor avoid potholes. Thus built-in polymer based rim protectors become necessary to lessen incidence of pothole induced tire/wheel failures.
Our wide 12 to 15 foot wide traffic lanes can cause complacency and inattentiveness for many drivers. Conversely my experience is that the narrower and more challenging the lanes in less developed countries/regions then the more the driver is required to pay attention and always make correct inputs.
Make things too easy and we become very bad drivers.
Future for motorcycles in an growing autonomous world is scary
