'STEP ON THE gas, step on the gas. Don't brake whatever you do,' shouts Hong Kong racing legend Albert Poon. 'Come on, back off. OK. Now push it, go.'
They are split-second commands that could mean the difference between the driver losing control and going into a spin, turning the car over, or worse.
Poon is recounting how he helped one of the 40 or so drivers at last weekend's Hong Kong Automobile Association (HKAA) assault on Zhuhai's 14-corner 4.3km race track steer his way out of trouble on a bend.
And Poon should know. In 1964 he became the first local Hongkonger to wear the Macau Grand Prix crown.
'He lost his nerve and braked. He got scared half way. You don't do that. You have to be quick or you go into the wall,' he says, relaxing in a Zhuhai hotel after a day on the track. 'When I'm teaching people how to drive, it sometimes sounds like I'm scolding them, but you have to remember that as soon as I start to say something it could already be too late.
'The Zhuhai track is relatively safe. If he'd done something drastic, the only thing I could have done was grab the steering wheel and save him from turning the car over. He was doing 80mph or something and had already lost his nerve. For me there was plenty of power to spare.
