Do you have any suggestions on the current parking problem?

The problem of parking is not only because there are too many cars or too few parking spaces, but also because the parking method is unreasonable. Like the parking lot near public places or entertainment places, if you look at the plane, her area is so large, but the demand for parking spaces is in short supply, so I think that kind of three-dimensional parking lot is really worth learning. However, the three-dimensional parking lot also has its own disadvantages, such as unreasonable design, insufficient popularity, some users may not be able to use it, and there may be some security risks in all aspects of use, which can be improved slowly. But this three-dimensional parking lot is really a good measure.
