Lady Godiva in her famous birthday suit can't have got more attention than this. I'm crawling around Parliament Square and off towards the Embankment in mid-afternoon London traffic in a Radical SR3 track car, and the way people are staring you'd think I was standing naked on the bonnet waving my unmentionables (I'm not).
The question that will no doubt be hovering at the tip of your tongue at this point, of course, will be: why? Apart from the obvious and slightly flippant 'because we can', it's largely because the car's owners, Dave Tilly and partner Liz Kerrigan, got in touch with PH to say they'd bought a new toy for their track day company.
Radical has sold more than 1000 cars since it was set up in 1996 and, of those, a significant number (more than 600) have been SR3s. But apart from a red car that once belonged to one C. McRae, and Dave Tilly's brand-new pride and Joy, we're aware of none that have been registered for the road.
On first acquaintance with the car you can see why. The ride seems to skim the ground, access is via an awkward clamber over the side sills and, once you're belted in, over-the-shoulder visibility is something you dream of.
I'm quite glad that Dave, who plans to hire the car out for track days, has installed dual controls. For him it's a simple survival technique - this is one of the UK's fastest tack cars and he needs to be able to control the over-exuberance of customers - but in this instance he uses them from the passenger seat to help me keep the car moving in the urban crawl.
I know it's a bit of a silly thing to do to take a car like this into a busy city, but the fact that it can cope with it is pretty incredible - and our gawping spectators as we pass through Parliament square are a perfect reminder of just how special cars like this are. I still think that we'll take it to a race track next time, though...
