Fastest woman on four wheels?

An actor who turned director, Lamont Johnson won a reputation in the early 1970s for his finely nuanced, perceptive direction of some interesting projects.

So they haven't selected the new Stig from the Stig Farm yet. Top Gear (BBC2, Tuesday) has yet to replace Ben Collins, who outed himself as the show's stormtrooper-lookalike boy racer in his autobiography – an act that was regarded as so abject by the BBC that it was as if Santa Claus had whipped off his fake beard to reveal that he had been Noel Edmonds all along (the clue was in the name).

Jason Plato wrapped up the British Touring Cars Championship by winning yesterday's first two races at Brands Hatch.

There's a famous Monty Python sketch called Philosophers' Football, in which Greece, represented by Socrates, Archimedes and Plato take on Germany, with Hegel, Kant, Marx and Nietzsche. High culture meets low. It's brilliant. Anyway, I was reminded irresistibly of this when listening to the distinguished art critic Brian Sewell on his passion for stock-car racing. The BBC has a habit, let's call it Stephen Fry syndrome, whereby once they've found a presenter who can do something, they want them to do everything, witness Mark Lawson and Andrew Marr. Good at politics? Here's a history series. A doctor? Why not take on some wildlife, and archaeology while you're at it. Famous for fashion? What about a book programme.

Programme-makers complain that without a big name, their pitch won't get commissioned. Journalists need to prove their versatility. Older presenters cry ageism if they are sidelined. Yet there are times when stretching the talent is justified and Stock Car Sewell was one of them.

The National Association for Stock Car Racing was born out of attempts in the 1920s and 1930s to set land speed records on Daytona Beach in Florida. Yesterday marked the start of the Daytona 500 which marks the beginning of Nascar's 60th season.
