So, I decided to ride the fail-train down to 0% accuracy, in an attempt to prove the "transits are rare!" claim that the tutorial makes.
I've no idea how many times I clicked through no transit, but on the entire trip down to 1% (because it doesn't seem to let you get any lower than 1%), I encountered ZERO 'no transit' slides.
To be fair, I played the "game" to start with, and even got to rank 3. During that 'serious' play I encountered 3 no transits, but as soon as I dropped below 50%, not a single one.
So maybe, just maybe, get the UI guys to take that line out of the tutorial, because it's utter bullshizzle.
