David Hough opens Proficient Motorcycling with a crash that unfolded in much this same way. It is harder to manage than the usual in-too-hot reaction because your time factor is cut seriously by your closing speed with the other rider (or car or bus or truck... er, lorry for you). I've had a couple of close calls with four-wheeler drifting over into my lane, so I do not push it on public roads. There must be enough margin to change my line any way I need to.
