@Bikers - when riding in a group along major Dual Carriage Ways or Motorways, pick a fucking speed and stick to it...
I was driving back from Holyhead on Saturday and as we left the port, there was a group of 6 or 7 tourers on a variety of machines leaving around the same time. I always travel this route with Cruise Control set to 75 (figuring this is actually near enough to 70 not to be concerned) and try to make smooth consistent progress. So I approach the group, indicate over and pass them all by in about 30 seconds, leave plenty of room before pulling back in and then continue on my way.
About a minute or two later, the lead biker cruises past. His manner was NOT "how dare you pass me" etc. I think his speed just gradually increased and past he goes. Then Bike #2 does the same. Now I'm fixed at 75 so I guess they must have been temporarily doing 80 or so to go past. I'm now stuck in the middle of the group - 2 in front and 5 behind.
Then lead 2 bikes slow to 65
I went for option 2 - I put the foot down, hit 90 for about 30 seconds and with a dab of oppo, I was gone.
Pick a speed lads - it's not hard...
