All of the above is unsustainable in London conditions. Most lights in rush hour traffic change for 5-7 seconds. If everyone left a gap of 5 meters around them only single cars would go through junctions at the time. On busy and narrow lanes, around Holborn, Victoria or Parliament Square I use my front sensors in rush hour to be no more than 30cm from car in front when stationary, just so at least three or four cars can fit between yellow box junctions and go through light changes in one go.
But I see red bus drivers in London now doing this tail to front thing, where they only leave about two inches of space from bumper of the bus, lorry or car in front after they stop in traffic specifically so the wobbly Boris bikers and "dancing lycrobats" cannot filter through the gap in front and start "staging" all over the place or position themselves in such way as to prevent slow bus from turning or going through short light change.
bus drivers are alright.. i cycle through oxfords street, tottenham court road etc everyday and tbh bus drivers are the best when it comes to it
