Ah you mean the nice boTollnecks, where you get into a traffic jam first (when driving a car) till you reach the booth. Once you drove through it, the road is pretty much empty. Which traffic management genius came up with this !@#$%^&*( idea?! Then they wonder how they can improve the traffic!

To get to your point, you can easily reach some amount like 40 kuai indeed. Quite ridiculous if you compare it to the fuel prices!
