Indeed, being somewhere else is of course the best thing, but once something DOES happen, jamming on the brakes while remaining pointed straight is easier to control than swerving wildly into the median. Because I've been autocrossing and doing open track events since 1999, I've had plenty of cars up over 100mph on the track. I actually locked up the brakes completely on accident on my 1988 Civic with a B16A at 115mph a few years back. Didn't even know they were locked at first. Nothing happened, I did not spin out or flip over 8 times. Braking is actually very safe.

Cars with soft suspension will nose dive a lot more than stiffly suspended cars, but Car and Driver does 70-0 mph braking on every vehicle they test. I've done maximum force braking in at least three different vehicles from > 100mph. It may seem foreign to most people, but it's really not hard to keep a vehicle that's traveling straight to remain traveling straight. Now whipping a car back and forth at 70+ mph? That's scary. In an Explorer of all things, and with swerving into the median? No thank you, sir!

In terms of risk exposure, you're many, many times better off just keeping it pointed straight and standing on the brake pedal. This is especially true for modern vehicles which have EBD and ESP to help you keep it pointed straight while braking.
