I have my temporary 'Cling film' screen in place, I doubt it's of any use but it keeps the PC mask wearing hippies happy.
When/If the NTA give us guidelines of what we can install rather than the wishey washey email they sent last week telling us what we cannot install, then I will install a screen that will pass suitability, hopefully the 25Euro FN (fer ambassadors) screen will pass suitability and insurance regulations.
The time will come that FN and all other dispatchers will be offering customers a choice of a Taxi with or without a screen, and priority given to cabs with a screen.
