To be perfectly honest, if this is the end of Top Gear, I don't think the BBC could ever get it off the ground as a "reboot" in today's PC times. I can imagine that the selection of the presenters to begin with would be subject to "reflecting the wide range of multicultural Britain, and balancing the varying viewpoints of motoring" (which I'm fine with, so long as those happen to be the "best people for the roles") If a lesbian, a homosexual and a green party member were selected "because they happened to have the best ability and chemistry - then that's brilliant. However often with the BBC these days, you feel they've been selected purely BECAUSE they're homosexual or of an "alternative view".
By all means BBC, make another car show - hell bring back the old format of "Watchdog for car drivers" such a show would be welcomed and useful to many.
However don't pretend it's going to be what the World knows as "Top Gear" because it just won't be.
