Somewhere outside Denver, a driver decided to teach a motorcyclist a lesson by spraying windshield washer fluid straight backward into my face at highway speeds. Maybe they thought it was funny. Maybe they thought I was following too closely. What they almost did was blind someone balancing on two wheels in heavy traffic. Motorcyclists already accept enough risk from distracted drivers, weather, and wildlife. We shouldn't have to defend ourselves from people who intentionally make the road more dangerous.
