I must admit im guilty of this too. Although i knew years ago that flashin doesnt do anything, i still do it out of habit at night if nothings about.

RS LOZWORTH, anyway if your a traffic light engineer mate, is there any chance you can come round this way and sort the timing out on 90% of the traffic lights cos there proper crap!
In fact sort londons centre out too mate cos there just as bad

Seriously though, whoever thinks up some of these sequences need shooting!
