We would have an application that would indicate the free places, and we would only have to wait standing for some to turn green to go there, without having to go round and round in search of the desired area.
This solution could help cities like Barcelona, where there are almost free green areas reserved for neighbors. Every citizen has an area where they can park, but finding a place in the area is hell any day at any time. There are thousands of cars that drive daily looking for their green area, and on many occasions, they end up desisting heading to the outskirts of the city, where it is free to park without having to be a neighbor.

The thing is, the solution they want to implement with Flash Park makes a lot of sense. Sensors powered by renewable energies that indicate whether an area is free or not feed an app that helps us save time. Sensors are designed to use 5G NBIoT technology as a standard for transmitting real-time data to track the status of monitored parking spots.
Logically, there are several problems you'll have to face, from people occupying a square without using the app while 10 cars head to it, to people who fool the sensor into thinking it's busy while waiting for the family car that's "coming."
The first problem could be solved in part with a 15-minute space reservation system, just like that of rental bikes, although that would not prevent someone from occupying the square during that time, since the use of the app would not be mandatory.
The second point would be solved by making the sensor unreachable by the user, other than something solar in the middle of the ground, as anyone could easily plug it. On their website, they indicate that their application uses a network of automatic parking detection devices that works without user interaction, of small size, resistant to adverse weather conditions and vandalism, so it seems that they have planned.
