While we're on the subject, can someone just clear something up for me? I always thought the shout of 'CAR UP!' was an indication that rider/s should get back in line smartish because a car was approaching from behind (cf. Adam's post earlier). Likewise the shout of 'CAR DOWN!' means a car is approaching from the opposite direction, and the shouter has seen it before the rest of the bunch has done so. Safety procedure. With me so far?
Is it really necessary to bellow 'CAR UP', 'CAR DOWN', etc, for every vehicle, in situations where everyone can see/hear the vehicle for themselves and everyone's in single file anyway? I mean, come on - there's enough pointless noise in the world already, without adding to it unnecessarily and straining one's vocal cords with all this bloody SHOUTING in the peaceful country lanes of, for example, Essex.
Just sayin'.
I don't think it matters whether people shout 'car up' or 'car down' - the message is clear and the majority of the people on our rides haven't any experience of CTC rides, so, frankly, they don't know either way - they just get the message that a car's coming. I shout 'car behind' sometimes because it's as plain as plain can be,
As for shouting - it's standard practice on CTC rides and they've been doing it for a hundred gazillion years, so I reckon they know what they're about. None of us are at our smartest at three in the morning, and it does no harm to be given a warning.
On narrow roads in Normandy we are really, truly going to have to get our act together. My plan, and it's a good one, is to have one, two or three cyclists a couple of hundred metres ahead of the bunch and simply wave down oncoming traffic. And the rest of us are going to have to single out pretty swiftly. I do think we can prevail upon cars coming the other way to pretty much stop, and we're going to do the polite people abroad thing and pull over to let cars by (that sounds tedious, but it's not going to happen very often), but with high-banked roads no more than four metres across there's going to be none of that half-wheeling mullarkey.
