Why Redhead?
Once I've overtaken on the motorway, it's obvious I'm moving back over, plus, if I've overtaken then I would only move over once it was safe to do so.
With regard to junctions, if there is no one around I would never signal. I don't need to signal for myself, I know where I am going. If some one appears, I put the relevant signal on.
Why would I make you mad? If you think about it logically, what I am saying makes sense. Signal when it benefits some one else, the rest of the time, don't worry about it.
How does the use of indicators reduce the risk of accidents? If the wrong one is used, it could cause one.......
