Coming back from Yea through Flowerdale behind a caravan. Caravan indicates he's turning right at the pub. There's a turning lane so I set myself to pass on the left. He's stopped then decides he doesn't really want to turn right and he needs to look at a map so he puts his hazard lights on and heads for a parking area on the left. http://g.co/maps/4n3p5 I'd slowed and was covering the brakes and blew the horn and managed to miss. Got to remember tourists in caravans get lost and do dumb things and don't use their mirrors well.
