Well, this is just cheating. McLaren has unending roads just outside the factory gates, roads the Senna will be very familiar with. Where is the drone footage of it tackling width restrictions and mini roundabouts in Woking? Not cinematic enough apparently, because the Surrey-based firm has gone to the trouble of dispatching a film crew to South Africa. And closed a road for them. A big long straight one.
The results, of course, are fairly spectacular. It's quite possible that Mad Max black is the Senna's best colour - certainly it looks the business here, through a lens filter and in a desert. The video purports to show the verification prototypes during hot environment 'high-speed' testing on the Northern Cape, although we'll bet all the money in our pockets that the only thing tested on the day in question was the driver's patience with a film director.
Either way, the thought of driving the Senna on the road is actually a rather tantalising one. The car, you'll recall, has already wowed Matt on the track, and there's further such activity to come in the very near future. But it's been made to work on the road, too, and no opinion can be called fully formed until that has happened. In the UK, ideally. On a week day. At 8am. Just north of Guildford. Smack bang in the real world.
