This was mooted initially but then dropped. They really are trying to get a "cleaner" car pool within the London suburban area.
However one point I have discovered it that the bike work is focusses on NOX emissions and tends to play much less attention on hydrocarbons and CO. Not sure how you can adjust an engine to give lower NOX, possibly dropping the compression ratio (but obviously not keen to do that)
