What does it mean to be a driver instead of a tofu man?

In the process of keeping faith, we need to be vigilant and lost. Never have the heart to fight with others, don't compete with others, what you want to win is yourself, being a driver, not being a tofu scum guy means that you need to be vigilant and lost in the process of adhering to your faith. This sentence comes from Taitai Fujimoto, the father of the car god Tuohai, an unknown tofu shop owner in "Initial D". Once he said to Tuohai: Do you want to compete? Oh, how are you? Don't you want to compete? Oh, what are you talking about? Come in and make tofu!
