Cheers guys, some great ideas.
Unfortunately the morning after posting the original question, some women from "Ididntseeyou.com" decided to do a U-turn from stationary traffic in front of me when filtering.......Ouch!

A bit off topic but am I right in my assumtion that she performed an illegal road maneovre?
