One of the big advantages of using Apex classes is the ability to leverage the power of object-oriented programming (OOP). OOP allows you to observe commonalities in data or behavior across your objects to share code or apply common processing across different objects.

An example of such a commonality in the Formula 1 world are rules; every aspect of the sport has a set of rules and regulations to comply with, such as drivers owning an FIA Super License, the weight of the car they drive should be at least above a defined minimum, and ensuring that a team has not exceeded the maximum distance while testing their cars. Such compliances are checked regularly, both before and after a race.
