I've seen this YouTube video, I live in Penrith and this company smells awful it makes me feel sick on a regular basis I wish they would shut down. The way the man in the video was treated is despicable I think the company must have something to hide.
As a cyclist can I just say that was not a safe overtake. We need far more room than that. If you don't believe me go read the highway code.
I have many posting s here proving just that.
You should've reported him to the Police.
