So automatics don't have a handbrake in the US? Weird. I had a Volkswagen Jetta automatic from work for a while (7 speed DSG) and it definitely had a traditional pull-up handbrake. But perhaps US is different.
The automatics I have driven had either that or a foot-operated handbrake to the left of where the clutch pedal would normally be. I wouldn’t pretend to know how a Ferrari does it though.
--- this guy has a video of him pulling the parking break while driving his Ferrari (because they told him to...!) - looks like it's a lever on the dash area --
