New TfL's HGV's can't see you for s*** poster

Apologies for not having read through the entire thread in case this has already been brought up, but isn't the elephant in the room here the fact we allow HGVs into built up urban areas?

It's a very good and important point, Paris banned HGV in their cities in the day time and have fewer fatalies (zero in 2011), of course Paris is a very different city compared to London so it's a bit of an unfair comparison, but does show the effect of what can be done to the No1 cyclist killer on the road.
