There are notable differences between those technologies, primarily that airbags do not take control away from the driver.
- Passive safety features, like seat belts, airbags, and crumple zones, are intended to reduce or prevent injury during a crash.
- Active features*, like ABS, TCS, VDC, and hill-start assist, can (and generally do) aid the driver in maintaining control of the vehicle.
- Automated systems like automatic braking and automatic parallel parking systems remove control of the vehicle from the driver.
I know I'm making a sweeping generalization here, but if you have to remove control from the driver, then that driver is obviously doing something wrong. Let's run through an example scenario to find the problem...
- People are rear-ending others without bothering to brake? No, that itself is not the problem.
- Why aren't people braking? Well, it could be that they're tailgating and simply didn't have time to brake; but, no, it's because those drivers have task-switched to looking at their phones or are fumbling with the car's touch screen interface--and, yes, some people are trying to also keep an eye on their kid(s) in the back seat--while their vehicle is in motion. A lot of people would stop here, but, no, that isn't the problem either.
- Why are these people willfully task-switching away from driving to activities that require the majority of their attention**, like texting, troubleshooting an uncooperative device, or trying to adjust anything on a touch screen interface? Seems like poor attitude towards driving. I think we can go a little further.
- Why do these people (Read: Not everyone) think that it's okay to get their multi-ton, rolling hunk of metal and plastic up to speed and then stop paying attention to it?
Okay, I don't really have a good answer for that last question; it could be any of a multitude of factors, from the woefully low requirements for getting a driver's license in the US to lack of experience or training, or even simply stupidity.
My points are 1) that these automated systems that take control of vehicles away from drivers are hacky workarounds; 2) mandating them on all new vehicles would not address the underlying issues; 3) and they would punish those of us who take the effort to focus on the act of driving, actively avoid distractions, and make a point of maintaining control of our vehicles. I have no problem with making these systems available, but I would not want one installed on my vehicle.
* Yes, there are instances where disabling these driver aids is appropriate. TCS needs to be disabled to get unstuck from snow; ABS should probably be disabled for autocross, especially on gravel.
** I'm defining "attention" in this context as any combination of mental concentration, eye sight (Taking your eyes off the road), and use of one or more hands that would remove focus from the act of driving.

Don't worry too much; it just redirects to Facebook. It's kinda sad the guys are too lazy to set up their own site for this.
