The problem with this electronic brake is not that it's electronic...it's that it restrains the applications of the e-brake.
A proper e-brake should have:
- a continuous application, from 0 pressure to locking the wheels
- proper ergonomics, easy to grab without looking, and easy to finesse the continuous levels of pressure
- 100% separate system in case the mainlines fail
While it's true that no e-brake runs on a 100% separate mechanism a proper handbrake on competitor cars have no problem doing the rest.
The push-button brake saves interior room and weight. On the downside it is now discrete, either on or off. It's also harder to access in some situations since a button is harder to find in the case where the car is out of control so the ergonomics are **** by comparison.

I have had this type of brake for a few years now on my SRX's and they work just fine. I actually like them a lot more. Who needs to look at the ugly old parking brake lever on their console anyway? Another old school thing that has gone by the wayside, which is a good thing.

Make it an option. Gimme a handle that I can use to actuate the brake exactly as I want to, the children that cant be trusted with something so complex as a handle can have their pushbuttons. Don't want to listen to them crying when they get their Nintendo taken away.

If the EPB is applied while the
vehicle is in motion, a chime will
sound, and a DIC message will be
displayed. See Brake System
Messages. The
vehicle will decelerate as long as
the switch is held in the up position.
Releasing the EPB switch during
the deceleration will release the
parking brake. If the switch is held
in the up position until the vehicle
comes to a stop, the EPB will
remain applied.

My 2011 CTS V has one, with my biggest complant being it's noisey when you first engage it, hopfully tht's been improved on the Corvette version.
Another misconception is that it will engage while driving. To many things have to happen and the computer tells you your stupid for pulling the switch up, as does the reaction of the car. The e-brake is disengaged as soon as the car transmission is put in gear, basically becomes useless, so no drifting in the C7 - well at least not with the parking brake

By the skid markings it surely wasn't the first!

I don't think so! I'm sure Chevy copied Cadillac on the E-brake, since they have had one operational for 3 years. The e-brake does not automatically disengage, it is ONLY released when you step on the brake and push the button down, no other way! I mean really whats the point of putting the e-brake on while driving, by accident, how stupid are you or your passenger?

From the Cadillac CTS-V 2011 manual page 9-37
Same goes for 2012 and 2013 models but found on different pages.
Automatic EPB Release
The EPB will automatically release
if the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve park brake lining life.
The EPB can also be used to
prevent roll back for vehicles with
a manual transmission taking off on
a hill. In a situation where no roll
back is desired, an applied EPB will
allow both feet to be used for the
clutch and accelerator pedals in
preparation for starting the vehicle
moving in the intended direction.
In this situation, perform the normal
clutch and/or accelerator actions
required to begin moving the
vehicle. There is no need to push
the switch to release the EPB.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑53 for more information.

He/she probably did a series of turns to perfect the procedure as well as to create a "driving line" out of tire marks. Then the other two Mini's were placed. Then a 20th turn was made. They don't show you that.
