Where are the brakes?

I just bought an Otto's Xiao Wang and tried it on the quiet Third Ring Road in the middle of the night. He drove happily. A big Ben overtook him from behind. When he wanted to overtake, he drove the big Ben guy away, leaned out and shouted at Xiao Wang, "Dude, have you ever driven Big Ben?" Then I drove away. It took Xiao Wang a long time to come back and run away. What's so smelly? Ah, bah. After a while, Xiao Wang forgot about it and drove around happily. When Big Ben came from behind again, he was very happy, as if he were taking a car. When overtaking, the guy who opened Big Ben shouted at Xiao Wang again: "Dude, you opened Big Ben!" " ".This angered Xiao Wang and tried to catch up, but he couldn't catch up and the dry gas didn't work. It didn't go far, little Wang Le. The bus crashed into the guardrail. Xiao Wang stopped to look at that arrogant guy's bear. When the guy saw him coming, he opened his mouth and said, "Dude, have you ever driven a bus?" Do you know where the brakes are? " .
