I'm not saying it isn't good as a quick fix temporary measure, but over here in Belgium this has been consistently used to pretty up the cycling path numbers while doing nothing.
We even invented "cyclist suggestion paths" ("fietssuggestiestroken" colloquially referred to as "paths of shame" (schaamstroken) [1]), which are not cycling lanes as they explicitly allow cars to ride on them, but just a color painted onto the right hand side of the car lane to advice cyclists not to ride side-by-side (which is their right within inner-city limits) but ride on the narrow painted strip behind each other, So this is an anti-cycling measure, and it still is counted as "cycling infrastructure".
Wow, you're allowed to ride side-by-side. Is that common in other countries?
Over here cars honk, even if 2 cyclists take only 1/2 a lane of 2 same-direction lanes and <5 cars pass in a minute. OTOH, if you ride the same, except the sheltered cyclist isn't there, they don't make a fuss even in moderate traffic - they just don't like you talking.
