Most obviously, it needs a new presenter. A woman, perhaps? Presuming that they stick with the three-presenter strategy, this would mean one of the oily trinity would have to go. However satisfyingly radical it would be to give him the chop, as the series’ grizzly figurehead Clarkson probably has to stay strapped to the prow. But would you rather see Hammond’s pitiless chirpiness, or May’s faintly-creepy-history-teacher schtick, consigned to Dave forever? The longer I think about it, the more attractive a show without either of them becomes. Actually, so too does a show without Clarkson. New blood would help Top Gear shake off its “lighten up” defensiveness about its blokes’ jokes, force it to be funnier, and make the existing presenters take a much-needed look in the mirror.
