Where I am I've never really had an issue with lorries, they always seem to be aware of where I am and pass with more than enough space. Smaller 7.5 ton (usually scaffolders) however don't seem to have the same awareness in my experience.
Sounds about right, pretty sure they either don't know most rules of the road or are such arrogant pricks they think they don't apply to them.
As a cyclist the 3 most dangerous types of vehicles I keep an eye out for are taxis, council vehicles and then police cars. All of which often pass me with 50cm of space between their vehicle and my handlebars.
Taxis are without a doubt the worst however. Fuck those arrogant, dangerous cunts.
Top quality post, love to see it! Thanks man :D
