If by a "perfectly good cycle lane" you mean a bit of paint, maybe with some plastic bollards at best, then I'm not surprised, you might think these are "perfectly good" but in fact they are not and paint alone is often more dangerous than nothing at all. There are two "perfectly good cycle lanes" in Birmingham, one of which I use reasonably often and prior to the cycle lane being installed every cyclist used the pavement, now they all use the cycle lane. I don't see the other one very often but when I've been up that way, and seen a cyclist, they've always been in the cycle lane.
Same with people using scooters on that road btw.
