As a local, I have always regarded the A82 as dangerous to cyclists, it is a motorway in all but name up until about Tarbert.
I had this conversation before in the touring section and was beaten into the ground with various accident statistics about how safe it was, but, those are just that, accident statistics!
These stats don't take into consideration all the other incidents that take place but generally aren't recorded. Seeing people cycling on that road during the day when it is at its busiest just makes me cringe, and no amount of statistics will convince me otherwise.
