The arrival of Rubens Barrichello at Honda should have been one of the stories of the season, but thus far things haven't gone the way of the Brazilian. The world is watching to see if he can strike out on his own, away from the long shadow cast by Michael Schumacher. But there's no escaping the fact that he's struggled to match new teammate Jenson Button for pace.
Of course, it's early days. The sport is so competitive now that even an experienced driver takes time to find his feet in a new team, as was the case with Juan Pablo Montoya at McLaren last year. Cars and their complex systems work in different ways, and in Barrichello's case there's also the small matter of the move to Michelin tyres, having been with Bridgestone since the company's arrival 1997.
If a driver is not comfortable, and the new package does not suit his driving style as well as the one he's just abandoned, life won't be easy.
