That's not a sharrow, that's a legally protected bike lane. Cars are required to yield if moving into the lane (just like any other lane) and can only do so when about to turn right or pull over to the shoulder. Sharrows in California look like this:

Agreed that the right turn across the bike lane is problematic (but still the driver's responsibility to yield when crossing).
