No doubt the motto looks like going not slow on a small road.

Any riders who have common sense will go slow and be on alert when they see a car at the road shoulder, with its wheels turned out.
Correct thing to do is to slow down, honk and, be prepared to swerve and brake if that car really cuts out.   
Also make yourself be visible, ride with high beam .
Bikers may be also at fault for not taking precautions, but that doesn't give the myvi the right to just cut out like this.  Even if the myvi had already signalled right.  Cannot just come out
If that was a lorry coming instead of bikers.  How?
