I read this a lot about bikes running stop signs. It is incorrect.

1. You pose a risk to pedestrians when you run a stop sign on a bike. A bike hitting a ped (especially a child or the elderly) can cause serious injury.
2. You pose a risk to other bikers when you run a stop sign ( I have been hit when biking by a stop sign running cyclist, it is not fun, you do crash and it hurts)
3. You pose a risk to motorcycles/scooters when you run a stop sign. A bike can easily cause a scooter/motorcycle to crash after a low speed impact.
4. And yes, you as a cyclists do cause a danger to 3500 cagers when you run a stop sing. Most of them don't want to hit you, will try to avoid you, and in the process may/likely run into any of the other users of the road.

So yes, a cyclist poses a significant danger to society by running a stop sign at low speeds.
