If you want CCTV footage, you are probably going to be more successful getting it yourself.
Go and look for CCTV cameras, and write Subject Access Request letters to all of the Data Controllers of those cameras.
If you leave it too long, the footage will all be recorded over. Be sure to mention to all of the DCs that you expect the footage to be saved and stored securely, as it may be used as evidence in civil and / or criminal proceedings.
It will cost you money - Sue the cabby for the cost.
