 it's like driving something completely different because they've got to drive that car really quickly, but they've got to know when to lift, when to brake, how to recharge the battery. Even this year, Oli Roland leading a race, I think in Italy, in Misano, ran out of energy with hundreds of metres to go in the race because he got that bit slightly wrong. The team had got that bit slightly wrong. So this is like playing chess in a 200-mile-an-hour-plus racing car on a track.
