WRT to what Safety Engineer said, I feel for you.
It was a refreshing change the other day to see ROSPA changing their tune and saying that kids should be allowed to climb trees and do other things that carry risk of small injury.
The big problem though, as the OP said is that no one seems to be able to take responsibility for their own actions due to the nanny state.
At the end of the day, if you walk straight in front of a car, it's your fault for not looking, not the car driver's fault for not being "strong in the force."
Obviously things like COAST mitigate this, but if you are trying to negotiate berlin cushions and other state imposed road furniture in a manner that will not destroy all of your suspension, you will rapidly become unaware of the situation around you, at any speed.
