Everyone said that driving from top to bottom and steep slopes tested drivers'skills. I really can't agree. It's more difficult for me to say the beginning of Jiuquhua Street. Navigation let us drive along Lombard street, driving to see a long car in front of us, the first reaction was traffic jam, and then look, frightened me, the car blocked up to the sky, because we are climbing, the slope is long and steep, to climb to the top, there are four or five red lights, while slowly climbing up the side of fear, to the penultimate slope, really angry, under the pretext of taking pictures of the car. The top of the slope is a crossroads, commanded by the police, and the passing car moves slowly and shouts at you. I guess I'm worried about the cars queuing up to climb the hill, so I want them to come up earlier. The view on the top of the hill is so beautiful that drivers have no time to enjoy it and have to go downhill again. I'm afraid all their attention is on the steering wheel. A short road soon came down. Courage, technology and cars are indispensable.
