Lightning has one specific feature that allows it to easily be bidirectional. The pinout can be changed via software, to adapt to any occasion, and essentially manufacture a new plug with a firmware update. This means orientation doesn't matter (without duplicating pins). This is a bit harder with USB, which has specific purposes for each pin.
It's not that hard to simply swap all the pins in hardware if the connector is reversed. You don't need to able to reassign every single pin to make that possible.
Lightning is overdesigned which makes it expensive.
You could say that the previous iPod dock connector was over-designed. But it wasn't, because it survived many years and many devices, with only a handful in between (like some iPod nanos) not being amenable to it years after its creation. We do not yet know what fate awaits Lightning. The odds are certainly tilted against it. Not only is Android popular and universally using Micro-USB (unlike when the first iPhone came out and phones had all kinds of plugs), but "smart wires" are increasingly antiquated: if you want to pipe music from your phone to your car, wouldn't you rather use WiFi than a cord? Sure, you need to plug in to charge much of the time, but now you can hand the thing to someone in the backseat and let them change songs. And any dumb USB port will charge any phone these days, which is good enough.
It clearly didn't? I'd say the iPod dock ecosystem and all the optional cables (like VGA, HDMI, digital out etc) more than justified the cost of the 30 pin connector.
> if you want to pipe music from your phone to your car, wouldn't you rather use WiFi than a cord?
No for several reasons (and since I haven't seen a single car with wifi music built-in, I'm going to assume you're abstracting wifi/bluetooth here into wireless):
1) Wireless drains batteries and I may not have a charger
2) Wired = charge-capable, likely charging.
3) Wireless setup requires authentication and configuration, often from the car itself. My 2012 Sienna is a great vehicle that is comfy on a road trip for 7 ppl, but it's BT implementation is a godawful nightmare. Setup is required to be initiated from the car, and can only be done through voice, and when you're not driving (even by passengers). Also, it tends to "lose" configs every once in a while. Meanwhile, the USB port just plays whatever's connected to it (we use mainly iDevices, so not sure about droids) and the in-wheel controls work fine.
No, because my car is going to LONG outlast the proprietary and most likely terrible app that my car's manufacturer would write for the current generation of one particular phone.
Cars should never under any circumstances ever have specific apps like Spotify, Pandora, and Bing. In 15 years, people are going to feel pretty stupid about owning those. The 3.5mm TRS connector, however, is a long term open standard that will still be working long after Pandora folds.

Isn't that the point? Its shiny at the time you buy it, but it quickly feeds planned obscelescence, increasing your desire to replace it later. Win-win for the manufacturer.
Really? Could you provide a source for this? I was under the impression that the 30-pin connector was (yet another) proprietary Apple hardware standard.
I'm struggling to find any source that directly confirms it, but it's most certainly the same plug used in this standard, and the Dell Streak which conforms to it.
The standard is for the specification of the pin layout not the plug. As all the links on the wikipedia page are broken and I can't remember the name of the plug itself, we're at a loss here.
PDMI certainly seems to be a copy of the Apple 30 pin connector, but it was introduced long after it. It wasn't electrically compatible, of course. To add confusion, certain Samsung tablets used a physical PDMI interface which was not electrically compatible with either PDMI or the Apple thing.
Overdesigned? Really? I'm not sure; it accomplishes the same thing as MHL, Slimport et al (which also tend to be expensive) and will be able to support USB3 when the time comes. It's far more futureproof than the old 30 pin thing.
It was underdesigned out of the box. From the documents I've read, USB 3.0 requires three differential pairs, whereas Apple only provides two with their proprietary connector. Plus, the built-in DRM means that it's a lot more difficult for hobbyists/experimenters to hack on it.
I'm sure they are doing this to preserve their patents, what is the point of an open standard if no one is allowed to use it?
I would really love to see a magnetic bi-directional cable eventually for phones/tablets. The Surface one is OK, but it doesn't snap as nicely as I think it could.
> I am mad at Apple for not making Lightning an open standard.
Lightning is just Apple's marketing term for Intel's Thunderbolt interface. The standard is available from Intel, and if it were not it would be more appropriate to direct your anger at Intel.
Thunderbolt is Intel's external, hotswappable PCI-e interface found on many Apple laptops. Lightning is Apple's proprietary interface found on iOS devices. Aside from being named after different aspects of the same natural phenomenon, they have nothing in common.
Well, being named after the same natural phenomenon is confusing enough. I often have to stop and think which is which. It's an understandable mistake.
You must have mistaken Light Peak for Lightening or Thunderbolt for Lightening. Light Peak = Thunderbolt, which competes with USB 3. Lightening is completely different.
