Thanks to the excellent advice here I have changed my cycling technique. I used to jump red lights, ride on the pavement etc but I've put all that behind me. I now cycle 100% within the law and it is great fun.
The advance stop box is a favourite. I filter to the front and whereas previously I'd jump the light and get out of the way of motorists, I now sit there, in the middle. When the light changes I often don't notice it straight away and as it takes a while to get up to speed sometimes only one or two of us get through the lights. In the rush hour.
Luckily I don't need third party insurance because I'm covered by motorists' insurance. I do think though that motorists should have additional training so that they are qualified to protect more vulnerable road users.
I have even bought some lights. It's legal to have them set to flash these days and if you get the angle just right it's possible to 'strobe' the faces of oncoming car drivers. Best way to ensure they see me eh?
I do all the hand-signalling stuff too. It's a bit precarious with all the potholes around but I know drivers don't mind the erratic unsteadiness this has on my riding.
I smile at motorists too as I know I'm doing what they want. Thanks all!
