• What is a "mandatory bike lane"?

    There's loads of bike lane along Uxbridge Rd. and near Kew Gardens but they are both rammed with cars daily.
    I was under the assumption that these were optional bike lanes (dashed line?) which aim to remind drivers about cyclists rather than give cyclists a lane.
    If that is the case, where can I actually see one of these magical mandatory bikes lanes? I guess they're fscking useless to anyone doing over 20kph?
