I've been wondering for a long time why the GMs and Chryslers of the world are so clueless about roboticizing our vehicles. Are they just stupid? Or are they locked into an irrelevant mindset, unable to think outside the box-on-wheels?
I think it's too late for the Big Auto industry. But there is plenty of opportunity for creative designers and engineers, to integrate new technology to create something that the public really wants, and that can improve the quality of life for all of us.
An example is this: atnmbl.
It's an encouraging design exercise for an automonous vehicle. The designers started by completely revisiting the driving experience. Think of all the things you can't do while driving: reading, sleeping, cooking a meal, enjoying a cocktail, playing a video game, logging onto Facebook, and much more.
Their conclusion was this: during driving, your entire life goes on
Then they started asking, what SHOULD the driving experience be like? Their conclusion was that not having to drive would be the biggest improvement of the experience.
Once they determined that driverless driving was a design goal, they researched the state of technology. Programs like DARPA's Grand Challenge have shown that, with GPS, machine vision and the latest sensor suites, the task of driving CAN be handled automatically. The proof-of-concept has been done, the earliest (very expensive) prototypes have been built and tested, and now it's just up to Moore's Law to make it affordable.
So, given that driverless vehicles are both desirable and possible, what would one actually look like?
Design firm Mike and Maaike (pronounced MYY-kuh) reached the conclusion that an automous vehicle would look more like a dwelling than a teardrop, or an insect, or a crouching tiger. They came up with a vehicle they call atnmbl, short for Autonomobile. The atnmbl has panoramic windows, an entertainment center, and a wide, comfy couch suitable for up to seven passengers.
The atnmbl not only focuses on efficiency of task, it redefines that task. If you aren't having to put your life on hold to drive, then speeding dangerously to your destination is not important. Acceleration and top speed requirements are reduced, because they just aren't important anymore.
What's important is that you are free to go about your business while you travel. You don't even have to worry about parking; the atnmbl can drop you off at your destination, and go park itself. Or, it can go take someone else somewhere. This eliminates the biggest waste that cars represent: vast parking lots filled with cars that are used twice a day.
If you own your atnmbl, you can offer it for hire at a price that is automatically negotiated for you. Or, you can just hire one by TXTing or calling from your cellphone.
Some models might be equipped with a microwave, so you can warm your breakfast on the way to work. Some might be equipped with a self-cleaning bath/shower, so you can drag yourself from bed directly to your commute. Or you could hire a long-distance sleeper model in the evening, spend a few hours enjoying the entertainment, retire for bed, get up and shower in the morning, and step out at your destination fresh and ready to go.
Some people will simply SEND an atnmbl to pick up their groceries for them; without drivers, and being completely solar-powered, it will be cheap to do so. Your children will be able to travel in perfect safety without you, because there's a reliable driver built into the vehicle.

Mark Ganter, Duane Storti and Ben Utela, from the University of Washington Department of Mechanical Engineering in Seattle, Washington, have developed a low-cost replacement for the materials their 3D printers use. AND, they've published their recipes.
Now materials costs drop from as high as $30 a pound to mere pennies. The result is that the UW has been able to open its rapid-prototyping shop to a wider variety of projects.
What's the new material? Powdered clay, mixed with sugar, maltodextrin or sometimes PVA. The fabjects are fired in a kiln just like any ceramic material.
Check out the recipe if you've built or are considering building a 3D printer.
