10+ over is moving into the arena of being imprudent under many circumstances. My thoughts in the other thread were primarily based on under 10mph over the limit.

That said, as it relates to cyclists it largely depends on the road. Under some conditions speeding drivers has no impact. In others even driving at the speed limit could be dangerous. Irregardless, there will always be drivers who speed, some dangerously. We would be better served by having higher training standards for acquiring a driving license. Closer to driver training in Finland.
