Twice round the lighthouse for £256,000,000.

Something with caterpillar tracks, fit for the crawl across the face of where foot has never stepped. Comfy seats. Well, as comfy as is reasonable. But you know it'll be the usual bucket seats. Looped straps along the bulkhead to hold onto in the event of a jolt. And you know there'll be plenty of those. And some boffin's variation on the Motorman's Friend, no doubt, for those little emergencies (I wonder what the ladies use?).

Doubtless they're already sketching the family saloon version, against the day when all this becomes as unremarkable as a trip to Blackpool or an inside lav.
