Ending up going through the ditch would hardly be minor, for the person forced of the road.
Attitudes need changing with regards what you can & cannot do as a driver to another road user. And this seems to be the perfect test case, for all who use the roads. She gets off, it'll be "open season" on everyone.
I've seen two riders mentioned & a group of riders mentioned, which was it. She was also on the wrong side of the road, by her own admission. The rider disappearing off the road to her right, would place her on the right-hand side of the road. Not the left(correct) side.
Was it speed that carried her over to that side of the road or possible use of a handheld mobile phone whilst driving? Both she's shown she's done in the past.
