When I lived in California I would lane split only in stopped traffic. I frequently encountered bikers who would be doing 60+ mph in slow/stopped traffic and lane split at high speeds during normal/low traffic. I always thought that was absolutely irresponsible. I may have been more cautious than the average biker, but I think if bikers followed lane splitting guidelines then there is nothing to fear from Autopilot and everything to fear from those who are supposedly driving cars themselves.
