Was reminded of a pet hate this morning... to those who wear head torches to see where they are going in the mornings;
Please remember that to be safe, not only do you need to see where you are going, the oncoming cyclist does as well (or they may well collide with you)
Please therefore direct your head torch downwards, ideally switch to lower power and (rant on) DON'T F*****g look straight AT me with your 20 gazillion lumen headtorch full on because if we collide you are going to need a proctologist to recharge your batteries you selfish bubbleheaded oaf!(rant off)
These lights are very impressive, very useful when doing 20-30mph down a singletrack, or whilst dicing with the traffic on a winters morning, but tbh, unless used with a bit of care they are extraordinarily selfish and rude on a nice clear wide track in the half light of dawn (old railway since you ask).
Just a thought.... ;-)
