-Our licence plate is separated in 5 sections :
-1. `AA`: Here we use `[A-Za-z]{2}` to match any combinaison of two letters between ranges A and Z or a an d z as we don't want to the licence plate to be case sensitive. We want to understand if the user sends us one in lowercase
-2. `-`: A literal dash character
-3. `999`: We use [0-9]{2,3} as we want to match any combination of 2 or 3 digits. (Scooters use 2 letters)
