Re: Cyclists take note lorries don't see you.
It doesn't matter what the rights and wrongs are. If you cycle up the side of a lorry, the driver can't see you. If you are in front of him, unless you are a long way in front of him, he can't see you.
The rights and wrongs DO matter. What you've highlighted here is that HGV cabs do not afford enough visibility to enable them to be driven safely on public roads. They have the WRONG design.
That cyclists do not appreciate this, and therefore behave inappropriately when in close proximity to an HGV is a secondary, not a primary, cause of accidents.
