How would that enable your car to be tested for compliance?

Compliance with what? Is the MoT not adequate? If it isn't, then it
needs beefing up for *all* cars, there is no reason to specifically
single out private-hire cars for that purpose.

There's currently an argument in Brighton about Uber drivers from
London being allowed to operate in the city (on their London
registration papers) because Brighton's requirements for the vehicle
are stricter - one of which is that cars MUST be fitted with CCTV
recording in-cab (for passenger safety, apparently)

And iirc Oxford tried to mandate CCTV that also captured the voices, but
got slapped down by the ICO.
