    Q. I've seen these new markings of a bike with two chevrons/arrows
    above it on the streets. What do they mean?

    A. These are "Shared Roadway Markings" which are intended to show
    where cyclists can ride on the street without being hit by a suddenly
    opened car door.


    Q. But on some streets, cyclists riding over this marking will take
    the entire lane. Aren't they supposed to move to the right?

    A. Not always.


    Q. Can't cyclists just look into parked cars as they ride and see if
    someone is about to open the door?

    A. This can be very difficult to do. Cyclists, along with all road
    users, need to constantly scan the entire roadway for safety. Checking
    every car for a driver is difficult to do without compromising
    attention paid to the road.


    Q. If I see these markings in a lane, is the lane only for bikes?

    A. No. This marking is used for shared lanes; lanes that are used by
    bicyclists and motorists. Shared lanes are different than bike lanes
    which are set aside for bicyclists and are marked by a solid white
    line and a different symbol.


    Q. So, if I don't see these markings, then it's not a shared lane and
    bicyclists aren't supposed to be there?


    A. No, cyclists can ride on any street in San Francisco except for
    limited access freeways with signs explicitly prohibiting cyclists.


    Q. Are these markings going to be on every street that does not have a
    bike lane?

    A. No, these markings will be used primarily on streets designated as
    part of the San Francisco Bicycle Route Network.


    Q. I've never seen these markings before. Why are they being used now?

    A. There has never been an official marking to use on streets with
    shared lanes.

    How exactly do 'shared lanes' differ from any other lane?

  3. Motorists get more confused when cyclists move to the middle of the
    road, away from the "sharrows" in order to turn left (in right
    driving countries)

    So they just add to the confusion?
