Grab and Eric,
When driving I follow the rules. Not to do so would endanger others. That is why the rules were made.
Cyclists pose no threat to other road users but are themselves utterly vulnerable.
Grab, non suicidal cyclists will not launch themselves into a space that they can not see far enough to be clear.
In 50 years of cycling I have been hit twice, both times from behind by vehicles going my way.
As a walker, do you never cross against the light when the road is clear?
As a walker would you endanger yourself in preference to making a technical infringement?
A cyclist is closer to being a pedestrian than a motor vehicle.
