"Oh Shit" moments...

Nice anticipation. You might have sat further out in your lane, stopping the second car from overtaking you (riding in primary position - cyclecraft), but there seem to be some drivers it's just better to get out of the way of.

Tried that, obviously not far out enough!

Earlier in the same ride I had two people overtaking me on the approach to roundabouts, left hand lane this time, but I was sat right in the middle of the lane, they just stamp on the accelerator and swing out into the right hand lane and shove the bonnet in front when they swing back in (and stop). Like you said, sometimes its just easier to back off.

I need to find a nicer way to get out into the New Forest from Bournemouth!
