As we all know, traffic jams on expressways usually last for a long time. Because of this, many drivers urinate on the roadside. I really felt a little confused when I first saw it, but it was inevitable after several traffic jams. People usually urinate every few hours, but some people urinate more often when they are nervous or in a bad mood. This is also called stress polyuria, and most people have it. Therefore, it is normal for many drivers to pee at the thought of high-speed congestion.
In addition to urinating in traffic jams, there is another behavior that is quite confusing, that is, after a long time of traffic jams, some drivers will get off and buy food and water from nearby car owners. In fact, high-speed traffic jams are rare, which leads most people to subconsciously think that there will be traffic jams. Usually drivers don't bring water and food when driving short distances, so once there is traffic paralysis, there will be a serious shortage of food and beverage supplies.
To sum up, I have encountered many confusing behaviors in high-speed traffic jams, but it is normal to think about it carefully. Most drivers will do some confusing behaviors for their own needs or emotional reasons after a long period of congestion.
