Epic fail

That's a drainage gully. I know council planning and designing is shit but it's not that shit.

Yes, correct. Quite often, engineers don't have the money for schemes to redesign the entire footway area, e.g. resloping the footway to get the drainage right across it, which is why you see a lot of schemes with these detached footway build-outs. Both the build-out and the main footway will drain into that channel.

also this. this one doesn't look so dumb, but that's another car parking space at the end of the bike lane, sometimes there's another car parked next to where the black focus is i.e. blocking the end of the bike lane

We tend to recommend central cycle gaps and obviously no car parking right across off-centre gaps. Is this a one-way street and the cycle track a contraflow track? This is genuinely an example of bad practice.
