The City Of London Police have announced that they will prosecute not only
drivers who go through the final stop line when the traffic light is reds,
but also drivers who go through the initial stop line before the cycle box.
This makes it noticeably harder to stop legally during the amber phase. I
don't see how the police can do this without lengthening the amber phase to
compensate, but even that doesn't really help. I think the only fair
solution is to remove the final stop line - since cyclists have no license
plates, the final stop line no longer serves any purpose except to allow the
prosecution of drivers who went through the meaningful initial stop line
during the amber phase, which will of course increase scamera revenue, at
the expense of large amounts of tax revenue when professional drivers lose
their licences in droves (drove being the past tense of drive.... hehehe).

Incidentally, I waited immediately behind the cycle box yesterday for the
green light for turning right from Silvertown Way to George Street, and
after about five minutes the driver behind tapped on my window and informed
me that the sensor only activated if I pulled my car forward onto the green
box!
