Surely that's not a protected bike lane at all? What's it protected by, a few flimsy sticks of plastic? I assume that when people talk about wanting protected bike lanes, they're talking about concrete jersey barriers at least.

To call that bike lane "protected" is like printing "please don't shoot me" on a tshirt and calling it a bullet proof vest.

Unfortunately, the definition of protection is not standardized, so one may consider flexi-bollards, parking stops, bollards, parked cars, planters, concrete curbs, and jersey barriers forms of protection. The standard term for a facility like this is cycletrack, but that term is not as commonly used.

For what it's worth, the term protected, in a traffic engineering context refers to exclusive movement through an intersection based on traffic signals. The most common example is a protected left turn as indicated by a left green arrow on a traffic signal. The other option for the left turn on either a solid green light or flashing left turn arrow is a permissive left where left turning traffic has to yield to oncoming traffic. Ironically, protected bike lanes rely on cyclists making a permissive rather than a protected movement for every intersection they traverse.
