Other ones are “it’s customary to shake hands will all the other passengers when entering a tube carriage or a bus”, “the number of yellow lines at the side of the road denotes the number of hours you can park for free” and “the best way to stop a London bus is to jump out into the middle of the road and frantically wave your arms at it”
I thought it was to symbolize there may be oncoming traffic and you may have to swerve. All those crazy Brits driving on the wrong side of the road and all.
I can’t really imagine any circumstance in which the lines would be especially apparent before the crossing itself was already clearly visible. If they serve as a warning that a crossing is coming, then they do so to drivers who have poor attention for seeing crossings.
No, the reason those lines are there is to provide a clear zone each side of the crossing so that approaching drivers can see anyone wanting to cross the road. If they weren’t there you could have cars parked right up to the crossing, thus blocking the view of drivers, and the very real possibility of a pedestrian suddenly emerging from behind one of those parked cars. Also they warn that you must not overtake on the crossing.
You have to bear in mind that, on the streets of London and many other cities, it’s actually very easy to for drivers to notice markings on the road. This is because the traffic is moving at about 2 miles an hour. You have time to look at everything.
Course, when it comes to markings for stopping to let people off or for parking, the drivers will always be on the look-out for road markings anyway - single vs. double yellow lines, and so on. They’re not something you have to look for all the time when you’re driving, only when you’re doing something that is prohibited in some parts of the road.
Abbey Rd itself is apparently a complete arse to drive across because of all the people doing Beatles reenactments with a camera-holding friend standing in the traffic.
Oh, there’s no way it’s an accident. I don’t remember them ever publicising it, they just allow people to discover it for themselves. Great, isn’t it? I wonder how many people don’t get the reference and just think “11? That’s weird.”
