Yeah it sounds bad but it could also be described as "Potential problem on Ferrari is so rare, that it hasn't been noticed since 2005"

No, it's been known for at least a couple of years, it took a lawsuit for them to do anything.

Hum - I believe this is what the hand brake is for no? Do Ferraris not have hand brakes?

Parking brakes are really just intended to hold a car still when parked. They’re typically not very effective at stopping a moving car, nor designed to.

I've forgotten to release the parking brake a few times, and was still able to drive, albeit with some resistance.

Ahahah this comment made my day, thanks.

The emergency brake in a car has a small fraction of the braking force of the service (normal) brakes. The emergency/parking brake typically acts only on the rear brakes and often via a separate braking surface that is nowhere near as powerful as the rear service brakes, to say nothing of the all-wheel service brakes.

In at least some cases, it's actually the same pads and rotors but just cable actuated, so that it can still work in case of total hydraulic failure. Wikipedia:

"In vehicles with rear disc brakes, the parking brake either actuates the disc calipers (with much less force) or a small drum brake housed within the hub assembly (the inner circumference of the disc is often used instead of a separate drum). This secondary drum parking brake is often referred to as a banksia brake."

I think at least the Ferrari 488 GTB that drove into the pond actually doesn't, it has an "electric parking brake" that you can activate somewhere on the dashboard next to the steering wheel, but not a normal handbrake. I can imagine not trusting this or forgetting where the button is if I were 2 seconds away from driving into a pond.

From the article it sounds like it affects ~1% of cars, and causes a complete loss of ability to brake. The one guy in the article linked in the comments had it total his Ferrari in June 2021, bought a new one, and it happened to the new one almost immediately too, in July 2021.

Doesn’t sound THAT rare for such a serious issue. Ferrari’s themselves are pretty rare though, so total numbers are low (23.5 K in the states, so 1% affected would mean about 235 cars).

It causes a complete loss of their ability to brake, but it actually increases their ability to break.

Hah whoops, typo, fixed :)
