Potholes? been around as long as I can remember. Once all that was needed was a slight of hand to point out the offending article.
But mostly if you were behind someone you just followed the wheel and all was fine, if you weren't on a wheel you looked out for yourself. No need at all for a signal.
And the tards that shout out 'holes' where, left or right or Afganistan?
And cars, they've been on the roads as long as I've been riding. Sometimes one comes up behind me and sometimes one comes towards me, I know this I don't need to be told. Look listen ride.
One good little signal is the back of the hand on the butt to signal moving out.
So tell me is all this constant jibber jabber unique to the UK? IIRC in Belgium the road is your look out, seems to be the same in France as well.
Sorry just had a great weekend in France without any of this tripe being spoken.
