Sounds like I'm right to me.
The driver of the following vehicle makes the decision.
There have been plenty of cases where the decision has been a poor one and there has been contact or worse.
The following driver always makes the decision.
It really isn't to do with semantics. It's more to do with A&E statistics, sadly.
there's been plenty of cases where the cyclist makes that decision extremely unlikely, and, further, it's up to us to exert ourselves in this regard.
Now, a little while ago, weather conditions forced a change in the route to a road that I had always avoided. I knew that if cars overtook then the cyclists (there were about 60 of them) would be put at risk. I took the back with a couple of strong riders and we formed a rolling road block, going up hill at about six miles an hour. One or two cars did get by, and one came very close to putting some of the slower riders in the ditch, but the rest formed a queue stretching back about twenty cars. Job done, as best we could.
Equally I've seen tail-enders not take up a defensive position, cars steam by, then the drivers realise that something was coming the other way, and swerve left in to the bunch. That's lackadaisical.
