I want compliance of bike safety laws – there is systemic value in the enforcement of such laws.
I want people to be good bike riders. They are good bike riders when they fulfill the definition of a good bike rider in my mind- one of the properties is one who rides safely. Fulfilling this definition gives extrinsic value.
Finally, I want bike riders to appreciate bike safety so much that they would be willing to educate their family and friends to ride safely. This gives intrinsic value.
