More on the Portsmouth Seafront, in a cycling town.
This is the Eastern end of the area, Eastney. Formerly fairly navy-centric -the building is the navy swimming pool, now open to the public.
At the end of this 30mph stretch of road -a road which closes due to storms in winter- there's a bend. On this bend, there is a hint of a bike lane. A hint. The dashed line on it means that cars are free to cut across the corner, which is what anyone taking the corner at speed would do.
The safe and sensible action for any fit cyclist would be to pull out, acquire the lane and so have no concern about cars swinging into you, but giving you more exit strategies if there turns out to be something like a parked car round the corner.
Which is not that unusual, given the way the bike lane ends, the road narrows and the first free-parking area near the seafront opens up. If even here, midwinter, there are cars in the way, high summer is going to be worse.
This is a bike lane for those willing to die, or at least injure themselves. Not for commuting, not for leisure work. You can't even bank into the corner at speed, what with the wall on the left-hand side. It has no value whatsoever. The only possible explanation for its existence is to push bicycles out of the way of cars. But even that is less than ideal, as they will still get in the way of taking the corner at speed, and then they will swerve out unexpectedly once the lane ends. Which makes it of limited value to anyone.
