No, it's because the limits were introduced in the Locomotive Acts primarily to reduce damaged roads from fast cornering by heavy vehicles and neither bikes nor horses are that heavy. The purpose has changed but that underlying framework hasn't as much.However, where 20mph limits are applied we should abide by them even if we are physically capable of going faster. We really shouldn't be blasting through urban areas as fast as we can pedal and pose every bit as much danger as a car driven at the same speed.
No, less mass means less danger but it's still a good idea to interpret 20mph limit as a general caution. I rarely get above second gear in the town centre.
I think we can all agree that it is possible for a cyclist to ride too fast for the situation and to put others in danger by doing so. My elderly mother, who uses a "walker" to keep her steady as she goes to the shops, has had youngsters on bikes weave around her at speed in a pedestrianised area, and it would only take a minor miscalculation to bring her down and put her in hospital. My elderly father died after a fall and the complications that followed. So it very much does matter that cyclists keep their speed "appropriate" around pedestrians. I know both of you generally think the same.
