Driver.cs

namespace RacingCalendar
{
    public class Driver
    {
        public Driver(string name)
        {
            Name = name;
        }

        public string Name { get; set; }
    }
}

Program.cs

using RacingCalendar;

// Part 1

Console.WriteLine("The 2022 Racing Calendar");

List<Race> racingCalendar = new List<Race>();

racingCalendar.Add(new Race("Italian Grand Prix", "Monza Circuit, Monza", new DateTime(2022, 9, 11)));
racingCalendar.Add(new Race("Monaco Grand Prix", "Circuit de Monaco, Monaco", new DateTime(2022, 5, 29)));
racingCalendar.Add(new Race("United States Grand Prix", "Circuit of the Americas, Austin, Texas", new DateTime(2022, 10, 23)));
racingCalendar.Add(new Race("Australian Grand Prix", "Albert Park, Melbourne", new DateTime(2022, 4, 10)));

foreach (Race race in racingCalendar)
{
    Console.WriteLine($"{race.Date.ToShortDateString()} - {race.Name} ({race.Track})");
}

Console.WriteLine("");

// Part 2
var driver1 = new Driver("Driver 1");
var added = racingCalendar[0].AddDriver(driver1);
if (added)
{
    Console.WriteLine($"The driver '{driver1.Name}' has been added to the race.");
}

Console.WriteLine();

// Part 3
var driver2 = new Driver("Driver 2");
var driver3 = new Driver("Driver 3");

var waitingList = new Queue<Driver>();
waitingList.Enqueue(driver1);
waitingList.Enqueue(driver2);
waitingList.Enqueue(driver3);

var nextDriver = waitingList.Dequeue();
Console.WriteLine($"Next driver: {nextDriver.Name}");

Race.cs

namespace RacingCalendar
{
    internal class Race
    {
        public Race(string name, string track, DateTime date)
        {
            Name = name;

        }

        public string Name { get; set; }
        public string Track { get; set; }
        public DateTime Date { get; set; }

        public List<Driver> Drivers { get; init; }

        public bool AddDriver(Driver driver)
        {
            if (Drivers.Count < 20)
            {
                Drivers.Add(driver);
                return true;
            }

            return false;
        }
