I have this theory that people move out of the outside lane of the motorway only if they really, really have to. Why else would people be such arses about it when they are slowing down a car travelling behind them?

It seems the best way to ‘encourage’ drivers to move over is appear behind them in a car with a seriously intimidating front end.

Contenders for this would be the Audi Q7 (Clarkson once said you could nail it to a church door to keep the devil at bay), the latest Range Rover, the Jaguar XFR-S and the Quattroporte.

However, you should pick the Maserati because it also has the advantage of being so rare outside of London that people haven’t got a clue what is coming up behind them in their rear-view mirror.

Sinister front grille + unknown quantity = rapid progress in the outside lane….
