The Datsun has been feed Prestone DOT 3 for 30 years...........the brakes on it are overkill / under stressed so it's not an issue. I also freely admit that the fluid gets flushed maybe every 5 years in this car. I live in a dry climate and the car does 6-8 events a year.
Awesome info about the most neglected fluid in most cars!
I would wager in cars with hydraulic power steering, that power steering fluid is the most neglected fluid in most cars.
Can confirm this is the case for my cars. I change brake fluid every 2-5 years. I'm certain that the power steering fluid in my 1991 Miata is the stuff that came in it from the factory.

Outstanding!! Yep, when I get a car that has any chance of seeing the track, the first thing done is brake fluid flush.
As AnthonyGS said, most neglected fluid in a car outside of the synthetic blinker fluid.

SRF or GTFO
I change mine once a year in all the track cars...and my cars see a LOT of track time.
Back in my pro racing engineer days, it's all we used under the Realtime tent.
One of the least hygroscopic fluids out there.

Endless 650 as good or better than SRF in my experience.

The Formula 500 gets Castrol LMA.

Nah people start crying if they have to use effort to steer. No one ever checks brake fluid.
