I think to say that the transporter wasn't trying to take you out allows for the people who drink over and then wipe someone out. He either knew what he was doing, should have been 2 metres away, or he didn't know and therefore shouldn't be driving.
Hope you got the roundabout driver for his actions.
I find in taking the correct primary position on the road one at least has somewhere to go to if a dangerous situation is caused by a bad driver. If you're already at the side of the road there's little to go to.
