Here are a few pictures and a teaser of some of these racing (and non-racing) events. (Porsche Boxster car card in the last picture included for comparison)
Honestly the most interesting part to me is that, aside from some of the Odds and Ends cards, racing events are cards you add to your hand, and then choose when to play when it's your turn. Odds and Ends cards are designed like power-ups; some might activate immediately, others have to be manually activated, and many require you to meet some conditions before you can.
When I landed on this idea, I had it. I had my "aha!" moment. This was the moment I knew I turned a dorky board game about cars into something potentially special. I viewed the kind of game you could play while chilling on voice chat that could rapidly get heated up (in the good way, or so I hope; be nice around the table!) with just the right elements.
Now to find friends to play with and playtest this... This is strictly a four-player game; I made my decision when moving to TTS, this really is the optimal number of players.
