Yeah in my area, instead of construct a dedicated one, they just paint on an existing lane and that took out half a car lane. It makes sense in theory but in practice there's no point to it.
They have many of these where I live. The worst part is that the police will fine cyclists and scooter riders for riding on the road. So everyone is forced onto the sidewalk where scooters scoot between pensioners, kids, and mothers with strollers. What an idiotic backwards system. Peasants, give way to cars. Fudalistic mentality.
Here in Lyon, France, the local government is removing car lanes downtown so we get wider bike lanes. Some are not happy about it, but if you look at the number of people passing through at rush hour, cyclists really outnumber cars, and bike traffic is never jammed.
My city (Lyon, France) is not perfect for bikes by any mean, but this is the kind of lanes they're busy building at the moment, so things are improving and bike traffic is skyrocketing.
We have a bunch of paths where bikes and pedestrians have their own lanes side by side (both way to narrow, but that's not the point). The pedestrian half is flat tarmac, the bike half is tiles like above. Really annoying.
