Re: A good thing in principle, but
Lorry drivers are paid by the hour and are not, generally in a hurry - more time is more pay. It is illegal for employers to do anything that might incentivise them to rush. However, cyclists would do well to consider that a large truck is a danger on a similar scale to a dragon of the same weight. 44 ton dragons are very dangerous. Getting within 4 metres is a bad idea, and within 4 inches is insane.
To those who say "why do we have 40 ton lorries in inner cities?" The answer is, as it always has been, sure they are more dangerous than transit vans, but they are much safer than the 15 vans that would be needed to carry the same load - and also cause massively less pollution.
As the Green party has rightly pointed out: if we got rid of the people, the pollution would stop!
