This cycle lane on Hanover Buildings is essential for cyclists since the lights won't change unless they use it. It also helps to separate cyclists from buses on this road. I have noticed this car blocking this cycle lane on several occasions despite the double yellow lines here.

Cars park here overlapping on the cycle path every day, preventing two cyclists from legally passing each other.

Unfortunately, we do not have any power to enforce this stretch of cycle lane parking – there is no Traffic Regulation Order on it. I have just spoken to a member of staff from Traffic Management who has advised me that the cycle lane markings in Burgess Road are purely advisory. The scheme was put in this way apparently because it would not attract any substantive implementation cost, and would not be subject to any objections from a public notice. - Highways & Parking Division

Car actually parked directly on top of the cycle sign.

Note pinch point in road which makes cycle lane especially important.
