HELP! I took a wrong turn and ended up in Pakistan. What do I do?

I was out for a leisurely drive around Whitby, North Yorkshire in my 1966 Jaguar and I unfortunately became slightly disoriented. Upon attempting to retrace my course, I found that I had strayed a little too far from home. I am now typing this from just outside Karachi, Pakistan. What do you propose my next course of action to be?
