not knowing the roads hard to say... if double whites thats just stupid...
but after the white line thread here recently and people pointing out double whites are now used indiscriminately and people ignore them whats right and wrong....
again, its not knowing the road in question. If blind bend, oncoming traffic, no clear escape route, then theres a good reason for the white lines and you dont ride like that unless you own a r1
but if on a straight and clear view then maybe I would consider taking the opportunity to get ahead on the basis the white lines were there for no reason...
but interesting to see the comments here, the comments in the white lines thread and compare to the thread about the traffic cops program where the guy got done for the same thing and a few people were up in arms over that in comparison to the guy who lost the lotus on the corner... complaining about police bias etc...
but at the end of the day, you never ride anyone elses ride, you ride to your abilities and comfort level. Their level of experience, ability, and personal choices on risks to take will be different to you. If youre not comfortable you DONT do what they do.
If it means you are 4 miles behind so what... at least you'll still be alive next year unlike the R1 rider by the sound of it...
