Great breakdown of how to get started. Top-notch.
On having a strategy, I would add:
Keep an eye on events
Avoid pre-game traffic - On event days, you will find the nearby areas to stadiums will have terrible traffic. E.g North London when Spurs is playing home. Avoid taking trips up to 1 hour before:
Target post-event demand - When events finish, there is usually demand or a surge. Park up on a side road and ask pax to come to you. They will be happy to as it saves them time.
