[QUOTE=AdamDZ;14006591] but not all the same responsibilities

[QUOTE]
I get your point. But a bike does not carry the same responsibility as a car. The damage you do on a bike has significantly less consequences then a htat of motor vehicle in the same manuever. Hence a cyclist is not required to carry liability insurance.
Not arguing that anybody needs to run stop signs or redlights. These should only be argued on a case-by-case basis, as I also have many lights that I stop at, and many stop signs that I treat as yield signs on my regular routes.
