Thanks for that Solorider. I can stop thinking about it now.
bludclot, it's a nightmare. Whatever you do, someone always tops it, eh? The first few Range Rovers had everyone raving about high driving positions, now ever second car has a high driving position. As you say, with cars starting to light up more and more during the day, it is harder to stand out.
Personally, I switch the lights on and off depending on what the day is like. On country roads where there's a lot of dappled light coming through the trees, I think it's easier to see other bikes when their lights are off, I use full beam when lane splitting on motorways and suchlike.
I guess you just can't take being seen for granted. I've made eye contact with cars at T junctions and had them pull out. What are you going to do?
