Back during WWII, gas rationing led to many people riding bikes, and too many accidents. The quick cure was to recognize that bikes are more like pedestrians than cars, so should ride on left side of the road facing auto traffic, so they can see and avoid danger from cars and trucks. That worked excellently.
Sometime later, the insanity of treating bike riders as cars got established, resulting in many deaths and injuries.
The path of a bike is highly unpredictable, since steering is also a part of balancing. The slower they go the more unpredictable the path.
Let's all spread the word and get government to correct the rules to make bike riding Safe!
