Have you ever noticed that trucks in Taiwan have flappy rubber straps in front of the front wheels? This has puzzled me for a long time. What are they for?
One friend told me that “it’s illegal for the air conditioner drain to drip on the road, so it flaps it into the air.” I don’t believe this. Tong Lian and He Xin buses don’t have that, and they definitely have air conditioning. In fact, those kind of buses seem to have water-cooled brakes, because you can always see streams of water on the road before turns as you approach the back of a tour bus on mountain roads. In addition, truck loads of wet dirt or gravel drip like crazy, so who cares about the air conditioner drain?
I live near the ocean and often see trucks full of fish (with melting ice) with drain pipes leaving a continuous trail of water on the road, which doesn’t hurt anything.
