You seem to be a cyclist so I'm surprised that you never appear to have been scared by a car passing you closely at 100km/h? Anything less than 2m away at this speed is likely to feel very scary to the cyclist. So whether there are two cyclists or just one makes no difference, you've likely got to veer into the next lane to pass anyway.
