Do you remember the [`road_intersection`](https://public.01-edu.org/subjects/road_intersection/) raid done in the Rust Piscine? Well, you
will have to create another traffic control strategy and its simulation. However, this time it will have to be done without traffic lights and with a smart intersection management strategy.
Most of the time overused intersections might lead to serious traffic jams on multiple roads, which wastes drivers'time and money, and also causes unnecessary air pollution. Additionally, according to a study from the National Highway Traffic Safety administration in the U.S., it is reported that about 96% of the intersection-related crashes had critical reasons to be the drivers fault, such as inadequate surveillance, false assumption of other actions, and turns with obstructed view.

[Autonomous vehicles](https://en.wikipedia.org/wiki/Self-driving_car) (AVs) are a promising solution to traffic accidents. An optimistic prediction is that AVs will be publicly available in the next decade, and thus traffic issues related to autonomous vehicles are also being extensively investigated.

Current intersection management strategies, such as the traditional traffic lights and other more advanced methods are designed exclusively
for human drivers. With the rapid development of AVs, new traffic strategies must be taken into account.\
This is where you come in. You will have to create this new traffic strategy algorithm, so that AVs can pass an intersection without any
collisions and with a minimum of traffic congestion.

This will be the way of controlling the current velocity/time/distance (depending on the algorithm you implement) of the AVs.
3. Each AV must respect a safety distance from other AVs.\
If it is driving with a high velocity and encounters another vehicle, it must detect that vehicle and keep a safe distance from it. It should not collide!

You are free to decide what is the safety distance but it must a strictly positive value.

5. You must implement physics for the vehicle, such as `velocity = distance / time`. Each vehicle must have a :
- `time`, this will be the time that the AV takes to leave the intersection
- `distance`, this will be the distance that the AV takes to leave the intersection
- `velocity`, this will be the speed of the AV at current time

A simple example of movement animation is imagining a vehicle with a route of `r`. This means that the vehicle arrives at the
intersection and turns right. If we render just an image of the vehicle facing down and it arrives to the point of turning, the rendered image
will continue to be facing down and not right, like it should be.

Your program must be able to generate statistics, as stated above. These must be displayed in a window, right after the user tries to exit the simulation.
The statistics must include:
- Max number of vehicles that passed the intersection
- Collisions if there was any
- Max velocity of all vehicles (Display the fastest speed achieved)
- Min velocity of all vehicles (Dislay the slowest speed reached)
- Max time that the vehicles took to pass the intersection (for all vehicles, display the one that took more time)
- The time starts to count whenever the vehicle is detected by the **smart intersection algorithm** until the end of the intersection, which is when the vehicle is removed from the canvas.
- Min time that the vehicles took to pass the intersection (for all vehicles, display the one that took less time)
- The time starts to count whenever the vehicle is detected by the **smart intersection algorithm** until the end of the intersection, which is when the vehicle is removed from the canvas.
- Close calls, this is when both vehicles pass each other with a violation of the safe distance.
