All RLJing is not equal - it's been pointed out many times that physical danger is not the same, risk is not the same, and now that psychological damage (which you brought up) won't be the same either. That's not to excuse the cyclists of course, but you shouldn't be trying to excuse the car drivers.
Err no. As a society, we should deal first of all with the most dangerous offences. With limited police resources, this means more serious offences must get dealt with on a higher priority than more minor ones. Oh hang on, that's how society and the police are already oriented.
