Emily/Molly started in Bologna at 10am and checked in to the Florence Pit Stop at 7:33pm, making this a 9h33 leg for them.
The directions from the Ducati Museum to Florence were given as follows (supplemented by the podcasts by Luis/Michelle/Emily/Molly and Derek/Claire):

Try it out on Google Street View and see if you end up in the right location?
David/Aubrey's mistake is completely understandable. The
street they're on makes a sharp right around a blind corner, and there's another road continuing straight, but under a different name. The blind corner road then takes a really weird loop that makes it look like a dead end, before continuing in the direction they're supposed to go. (Luis makes mention of this in his podcast, and Derek/Claire seem to have made a mistake at the exact same turn.)
Rich/Dom got off the A1 a few exits early at Firenze Scandicci instead; this would have got them super lost and driving unnecessarily through city streets.
