Charging cars by USB would go a good way about solving the problem of the lack of outlets. Use a fast USB charger for best effect.

Seems a bit lack-luster compared to the newer-gen SoCs. Power consumption is now the question.
As others have stated, these chips undergo rigorous testing and validation and hence time to market is much longer than your average cell phone/tablet.
Tegra 3 is indeed 3 years old..it taped out in February'2011. As you state, given the rigorous testing and validation, and then to be designed in by car makers based on their own development schedules, it is not that surprising to see such an old chip being used. However, their automotive division has been trying to enter this market for a long time, and they have sold quite a few Tegra 2 based solutions already.
See my post from September 2010 here - http://forum.beyond3d.com/showpost.php?p=1472478&postcount=329
Keep a lookout for Tegra SoC's in Audi's upcoming cars, ive seen some development boards for those
Edit: To add, they weren't just development boards, there were also full blown dashboard prototypes and mockups.

If you want to use PCIe, Tegra 4 doesn't have it. Only Tegra K1 can replace Tegra 3 for all uses.
I'd be interested in what kind of I/O there is between the Tegra and "the car".

Looks great, 2x single thread perf per core compared to 2.3 Ghz A15 since AnTuTu scales linearly with core count

This is a link showing CarPlay. At the very end they say that the apps are actually running on your phone, and that there is a wired connection between the phone and the car.
So this seems indeed like a case where Apple is sending rendered images to the car display. It probably also explains the every so slight lag between her touching the screen and the screen reacting.
Finally, they show that this CarPlay is a layer on top of the regular car computer: you can switch from CarPlay to the standard Ferrari interface.

TK1 will be used inside Lenovo's soon-to-come 50" 4K Smart TV: http://www.gforgames.com/gadgets/lenovo-4k-smart-tv-nvidia-tegra-k1-40871/
Due to advances made in Tegra K1 (and subsequent Tegra SoC's), Tegra Automotive is able to reach far beyond digital instrument clusters: http://www.pddnet.com/articles/2014/03/inevitable-future-driverless-cars
Note that the actual TK1 SoC will be in the single digit watt range, while a full driver assistance platform (including cameras, sensors, and various other components and processors in addition to TK1) will be close to 50w, which is an order of magnitude less power consumption than previous driver assistance solutions.

Will it get 15 years of security updates?
What OS does it run?
The trend of "smart this" and "smart that" is very worrying. In old times stuff didn't get updates but was not connected to anything (VHS or DVD player firmware, oven's micro-controller) but nowadays you have Android and whatever creeping into connected appliances that ought to last 10-20 years, possibly 30 years.
So what's up. New leglislation is probably needed for this stuff. We run the risk of being watched through the TV's webcam and what not. (I'm serious, such a Samsung TV was exploited through a software vulnerability, which gave attackers control of the camera and access to files, it was of course patched)
Support is an uknown, some phones only get two years or less of updates.
Will there be a means to destroy the Tegra computer part and keep the TV, or at least destroy all connectivity? (wireless, USB, ethernet.. ethernet over HDMI or displayport is a problem)
Nvidia probably provides source code to make their chip run the car's OS of choice. But the kind of security updates you're talking about is the typically responsibility of the car component maker. The component makers are way too paranoid to trust others on this. (If only because tech companies often don't have the longevity of a car! )
Cars have been full of CPUs for many years. And cameras are not exactly new either (my 6yo car has a rear camera.) And neither are wireless links (OnStar must be, what, 10yo by now?)
What exactly don you want legislation to say? "Bugs are not allowed!"

If you realize what car dealers charge you for map updates on GPS units, you know it's not a good idea to invest too much on car electronics that car manufacturers and dealers provide the updates for.
Not to mention OEM GPS is a ripoff to begin with.
Maybe all these mobile platforms supporting car use should support after market manufacturers.

The gold standard for me (not saying a lot because I haven't seen a lot of smart dashboards) is the Tesla console. I don't see how you can get this kind of functionality and integration with an aftermarket kit.
And, yes, I understand that the car options are expensive, it's not a hard concept. But that's what it takes to avoid a dashboard full of clutter, and charging cables on an otherwise very neat design, so be it.

Maybe cars use something like QNX or a hardened, supported linux and expose as few functionality as possible. Then, I wonder how you update it when you have a critical security vulnerability like the recent GNU TLS one.
My comment was about the smart TV foremost, you put the security at the mercy of a hardware vendor that churns out models a lot, it's like smartphones but there may be more apathy even.

Ford just announced that they are switching to QNX:

If you're buying a car now, would you pay thousands more to have some electronics package which replicates a lot of features which a mobile device could provide?
Would you sign on to another LTE data contract just for your car?
It's a nice to have, a big screen on your dash that has its own apps and GPS as well as displaying what is on your phone or tablet.
But would you buy a car with a several thousand dollar package just to get it if you can get the same car without that package?
With some luxury brand imports like Lexus, they only offer cars in certain regions which already come with several of these packages. I think the German marques play this game too, so there is rarely any inventory of cars which just standard equipment, close to the base price.
It's like having to buy a package of TV channels, most of which you won't watch, when you sign up for cable TV, instead of being able to get just the channels you want a la carte.
That's the only way these elaborate car systems will get sold.

Surface 2 with LTE announced:

That has to be Icera i500. The HSPA+ and 4G LTE bands supported in Surface 2 LTE are the same as Tegra Note 7 LTE, and Icera i500 has already been certified on AT&T and Vodafone wireless networks.
