There certainly were historical problems with cars being damaged by lorries, but I haven't seen/heard/experienced anything for a while. I tend to avoid parking in potential 'danger' zones just in case.

Lorries drive along Waldenshaw Rd, down Manor Mount onto David's Road and then on to Pearcefield Avenue, they then drive up towards Manor Mount again before reversing into the loading bay area. They don't often cause congestion - I'm only ever delayed for 30 seconds or so while the reversing takes place. It's a bit of a pain if you get stuck behind one on their return leg along Waldenshaw Rd though, but this is a relatively rare occurrence.
