Nothing wrong except that it's an accident spot because of impatient motorists overtaking cyclists on a blind rise/bend. The bushes don't encroach. The road falls away at that point. But you are correct. Nothing illegal there. Just not smart.
So, the issues are that some motorists are impatient, some motorists overtake where they shouldn't, some motorists drive too fast and some motorists don't like to be held up.Where I cycle (seafronts) there is/are often cycle lanes, or shared pedestrian/cycle lanes but often see many 'hardcore' roadies in the narrow and fast moving (traffic wise) road. As you mention - there is nothing illegal to this - is it just a bad idea? to hold traffic up at narrow lanes just so you do not have to cycle over the bumps etc in the actual cycle lane?
+1. As the Pompey area people know, there is a segregated cycle lane on Southsea seafront. I use it going east-west. West-east: the road. Why? Simple. Prevailing winds etc mean I can sustain 20-25 mph over a mile. Despite what some uneducated drivers seem to think, I am perfectly entitled to use the roads even when there is a dedicated cycle lane. And doing that speed in a narrow lane with others riding the opposite direction, pedestrians frequently stepping straight into it, the risk of being doored....no thanks. And at the end of the lane, I'd have to cross over the road anyway because the whole thing was badly conceived.So, the issues are that some motorists are impatient, some motorists overtake where they shouldn't, some motorists drive too fast and some motorists don't like to be held up.
As the problems are all because of some motorists behaving illegally or irresponsibly, wouldn't it be better to sort out the motorists rather than the cyclists who are doing nothing wrong?
