I was going to avoid doing all 3 at once, but then I realized so many of the gates are tied to a billboard. Then it seemed like the rest led to jack spots. So I decided to just do all of them in one go. I already have all the most wanted races done. The only event i have left is that final speed run. I just realized this morning that I should probably go ahead and do a few of the races in the crazy named car then use it for the collectibles to help unlock some pro mods to help with that race instead of grinding them out later.
I have definitely made use of the jack spot jumping. I am really thankful that is in the game.
