Going at an unusually low speed can attract police attention up here in Oregon.  The legalization of recreation cannabis has increased the number of non-alcohol intoxicated drivers.  Apparently one sign of DUI of cannabis is going too slow for traffic conditions.<p>AFAIK no driverless cars around here (yet), but there are plenty of other potential hazards for motorists, like pedestrians and bicycles on narrow, twisty, dark and wet streets this time of year.<p>Ideally it calls for everyone to be patient, careful and vigilant.  Above all be thankful if born with great reflexes, on the road alas only a few are so gifted.
