Lea Bridge Road/Walthamstow mini Holland

You see what I'm suggesting by parked cars and vans though? Crossing the road/cycling along the road is much more dangerous when there are bumper to bumper cars parked! This has to have been a consideration?

Of course, parked cars are a huge problem (although in a sense a blessing in disguise, as off-street car parking is far worse--it can't be managed like on-street car parking can). It almost sounds as if you're talking about queues of (congestion-causing) stationary cars rather than parked cars, though, or am I imagining that?
