'Cause it's the cyclists that need educating...

My random rules of cycling -

RLJ and pavement cycling are 100% fine so long as you're not caught, you do not make pedestrians feel threatened in any way (ie don't cycle on pavements near pedestrians) and you take responsibility for your own safety.

How do you know that you won't get caught? how do you know for sure that there's 100% no people on the pavements (and it is a pavements for peds), what happen if a child darted out of the shop onto a pavements? how are you able to fliter back into the main traffic stream when you decided that pavements is too full? etc.

that's probably the most irresponsible sentence I've heard from you.

Undertaking at lights should not be done unless you are 100% sure that you will be in front of whatever you are undertaking before the lights turn green.

Wouldn't it be easier to just not do it and overtake instead? (or wait behind a vehicle) so you won't need to make sure that you're 100% sure it's okay to go ahead?

Oh yeah, try indicating ALL THE TIME (peds want to know whether it is safe to cross, cars might know what you're gonna do if you indicate). Try letting cars out in front of you or past you occasionally.

There's a risk in indicating all the time, if you do so, you'll get in the habit of doing it every time you need to make a manoverve and quite likely forget to look behind before you signal, and looking behind is vital to know what's going on with the traffic behind you, for example like a cyclist who's going to undertake you and propelled himself toward your overstretched arm instead.

Only indicated if there's vehicles behind you, if there's no vehicles, don't incidate.
