Now the group of people who share rides, share accommodations, and share food has emerged; this is also a new way of life in an era where resources are more fully utilized and mutual benefits are achieved. One must realize that living in this era is not easy, and the pressure on white-collar workers is very high, so in life, one must be meticulous about everything. Therefore, it makes sense that the "sharing" group has appeared. Ideally, if one wants to take a taxi somewhere, it's definitely possible to find a ride-sharing opportunity that can take you anywhere you want to go along the way. However, such taxis are hard to find, and some taxis and passengers may not necessarily be willing. If a carpool sign like this were placed on top of a taxi, and such a carpooling mechanism could be formed, there shouldn't be any problems. After both the passenger and driver agree to carpool, the destination would be displayed on the carpool sign, and then anyone going to these places along the way could take the taxi as a shared ride. This reminds me of the popular hitchhiking travel method abroad. Besides taxis, in some tourist areas, drivers willing to let others hitchhike could use such carpool signs, and when travelers want to hitchhike, they could take these cars. Drivers can charge a small fee for the road and have someone to chat with on the journey, which is convenient for others and oneself.
