But also a car lane.
What it really means is you're not supposed to pass each other in that lane (it's used where there isn't room for that), but rather use it serially one after another, unless you can leave the shared lane to pass the other party.
"Bicycles may use entire lane" is a much clearer sign for these situations, and has the same actual meaning (or if you want to quibble, "sharrows" change "may" to "should" by directing cyclists to a position that is literally "taking the lane")
