Played bunker track without showdown
Today I played Sine City with fuel instead of tickets :D
Using the same method as before by opening a notification saying a friend passed me on Sine City, it showed the leaderboard. I was curious if anyone had set a time with donkey, but the donkey tab was empty. I pressed start race thinking it would say showdown special but to my surprise it started the race! I was able to choose any bike, by scrolling left and right it showed all 10 bikes.
Improved my time a little, got to spin the wheel

Checked the top of the leaderboard
Set the one and only donkey time :p
I was also able to use the restart button and use the leaderboard to race ghosts.
So improved my time a little more
Now I am not sure the race can only be started while looking at the donkey tab, because I did not try to start the race while looking at another tab. Maybe someone can confirm if you get the chance? Maybe the tracks are unlocked now for everyone and will be on the map soon, I hope, would suck if the donkey is needed.
