A single bicycle or pedicab (i.e., a bicycle with a pbuttenger cart) isn't what upsets me about bicyclists. Eventually they pull over, or an opportunity exists to pbutt them in safety.
However, what upsets me about bicyclists are those damn MFFY packs of bicyclists that are the real hazards on the roads. They often ride along the coastal routes with cars parked curbside, and they often ride double or somtimes now even triple file as a pack, spilling well over the bike lane marker into the right lane, as they impede the right lane traffic flow well below the minimum posted speed limit, as the pack carelessly swerves along to avoid the curbside parked cars without paying attention to the vehicles that may be travelling behind them.
As such, the left lane also becomes jammed up due to cars partially or fully changing lanes to avoid the reckless bicycle pack on the right. And pbutting the pack by remaining in the right lane is often difficult because it's not exactly certain the next time they will swerve again.
Now, the curb-divided bike lane, rather than just a painted lane marker, is an elegant solution that is not used enough. Some of those even go one step further and also provide a guard rail barrier along the curb divider.
Or, if bicycles want to continue to ride along the roads like a car, then they should follow the same rules of the road, like a car, signal any lane change, and pay attention to the traffic behind them as well as in front of them (i.e., turn out when the required number of cars is backed up behind the bicyclists). I tend to laugh at the SHARE THE ROAD signs because the cars already do that, it's the bicyclists--usually in packs--that don't share the road.
And as final point of interest, even when motorcycles ride two across in a single lane intended for motor vehicles, they remain within the lane markers of the lane.
