According to the criminal complaint, Briones tried to drive away, leaving the woman behind."Naked woman thrown from car after crash"
A witness was able to grab his keys.
Police found Briones with one shoe and his shorts on inside out.
The answer lies in another question. How can PVC — polyvinyl chloride, a commonly used type of plastic — be the stuff that makes tough, rigid sewer pipes and, simultaneously, be the stuff that makes floppy vinyl signs and cheap Goth pants?
"PVC is hard stuff. But if you put in a lot of plasticizer, you can get it to be soft," explains John Pojman, a chemistry professor at Louisiana State University. At a molecular level, PVC is a dense thing. Imagine a slinky in its stiff, compressed state. The plasticizers are chemical compounds derived from coal tar. Mix them with PVC and the small molecules of plasticizer shove their in between the densely packed PVC molecules. Imagine stretching the slinky out so that its coils are now wobbly. Same thing happens here. The more plasticizer you add, the less rigid the PVC.
And it's the plasticizers that produce that smell — the one we associate with the vinyl interior of a new car.

In 1952, LIFE published an article about Louie Matter, a gearhead who tricked out his 1947 Cadillac with a shower (seen at right), drinking fountain, tape recorder, washing machine, stove, "and a bar with spigots for whisky, water and soda." Oh yeah, and a dashboard hookah too. This, my friends, is the definition of "bow-tie classy." "Shower? Check. Washing Machine? Check. Hookah? Check. Let’s Ride"

Jason Torchinsky of Jalopnik says: "I have a post up that I though BB people may be interested in, about if it makes sense to standardize UI for cars -- most of our car-folk readers are against it, but I think a more general audience might feel differently."
1. Common Controls
Really, we're just about at a standard for these, but not quite. It's being so close but not quite there that makes this category so annoying. Since I drive a good number of different cars as part of my work, I encounter many, many different dashboard and control layouts. It's not really a big deal to adapt to a new car's controls, but it's not entirely seamless, either.
For example, I'll sometimes drive off in an unfamiliar car, and a minute or so into my trip realize I need to defrost/defog the rear window. So I can, you know, see. This particular act is almost always confounding — the rear window defogger/defroster is by far the most randomly placed control in all of motordom. Sometimes it's snuggled up with the HVAC controls, all indistinguishable from the windshield defogger, with its magic rising snakes icon. Sometimes it's over on the left, near where the mirror controls sometimes are, sometimes it's stuck on the center console, and I've even owned a car where it was an unmarked switch under the dash. Nobody has any idea where to put the damn thing. From what I can tell, where they end up placing it seems to be dictated by wherever the guy who realized they forgot it slapped it on.

In the New Yorker, an essay by Gary Marcus on the ethical and legal implications of Google's driver-less cars which argues that these automated vehicles "usher in the era in which it will no longer be optional for machines to have ethical systems."
Your car is speeding along a bridge at fifty miles per hour when errant school bus carrying forty innocent children crosses its path. Should your car swerve, possibly risking the life of its owner (you), in order to save the children, or keep going, putting all forty kids at risk? If the decision must be made in milliseconds, the computer will have to make the call.
Police in Saarland, Germany, pulled over a man for speeding. In his car, they discovered an unusually extensive mobile workplace: a computer set up for use from the driver's seat, a printer, a router, a wireless networking dongle, a dash-mounted navigation system and a mountain of other junk. He was fined for having "unsecured items" in his car, according to reports. [Times Online]
For the first time ever, the winner of the 2013 Motor Trend Car of the Year is not powered by an internal combustion engine; it is the all-electric Tesla S. Not surprisingly, Motor Trend is also spinning the news as a big win for American innovation. "2013 Motor Trend Car of the Year: Tesla Model S"
For 70 years George Barris has been "taking ordinary vehicles and mutating them into hell-for-leather roadsters," many of which are now part of automotive history.
"Others have been immortalized on television and in the movies," writes W.J. Hennigan in the Los Angeles Times.
"He turned a 1955 Ford Lincoln Futura into the Batmobile. He stretched out a Model T body and, with a few tweaks, made it into the ghastly vehicle that the Munsters drove in the TV show."
There's a video, too (non-embeddable).

A driver tried to drive into the Chaussee d'Antin La Fayette Metro station in Paris on Tuesday, reportedly having mistaken it for a subterranean parking garage. The driver, who gave his name as Johan, told AFP: "There's a sign saying 'Haussmann Parking' right in front (of the Metro entrance), and ... I made a mistake."

We've talked about arXiv here before. It's a pre-print server for scientific papers in the fields of physics, mathematics, and computer sciences. Basically, what that means is that scientists can post papers to the site without first putting that research through the process of peer review. And that's not a bad thing. ArXiv is a great way for scientists and mathematicians to critique each other's work and do a little bit of vetting before submitting the paper to peer review. That's why the faster-than-light neutrino reports were published on arXiv—the results looked so crazy that the researchers wanted their colleagues to figure out what had gone wrong before a prestigious journal got involved. It's a way of collaborating.
The other nice thing about arXiv: It's a great home for interesting data that doesn't necessarily have a place in a formal, peer-reviewed journal.
Case in point: "The Proof of Innocence", a paper in which physicist Dmitri Krioukov uses math to explain why the cop who stopped him for running a stop sign was clearly seeing things. Physics Central summarizes the first step in this defense:
When Krioukov drove toward the stop sign the police officer was approximating Krioukov's angular velocity instead of his linear velocity. This happens when we try to estimate the speed of a passing object, and the effect is more pronounced for faster objects.
Trains, for instance, appear to be moving very slowly when they are far away, but they speed past when they finally reach us. Despite these two different observations at different distances, the train maintains a roughly constant velocity throughout its trip.
In Krioukov's case, the police cruiser was situated about 100 feet away from a perpendicular intersection with a stop sign. Consequently, a car approaching the intersection with constant linear velocity will rapidly increase in angular velocity from the police officer's perspective.
Krioukov's basic argument: The officer thought he saw Krioukov speed right through the sign. But he was wrong. Instead, Krioukov stopped at the sign, but stopped very quickly and sped up quickly, both of which happened out of the cop's direct line of sight.
It's worth noting that this argument was good enough to get Krioukov out of a $400 fine.
A couple of years ago, Cory posted a really interesting story about the mathematics behind seemingly cause-less traffic jams. It's pretty interesting. Shorter version: The researchers think jams like this are caused by one person braking, and the response to that slow down moves through dense traffic in a way that is mathematically very similar to the shock wave from an explosion. Once you have enough density of cars on a road, jams are inevitable.
Cory's post included a simulation, showing what the mathematics might look like in the real world. Basically, a computer algorithm figured out how drivers would behave if the mathematical theory were correct and turned that behavior into a little cartoon of cars moving around a track.
But here's the really cool thing. This effect has actually been demonstrated in meatspace. Yesterday, a friend sent me a video from 2008, showing real life drivers behaving in almost the exact same way as the simulation video from Cory's post. That's what you see posted above. Now, these are not exactly real-world conditions. A flat circular track may, or may not, be a good representative for what happens on the highway—I, for one, would be interested in seeing how on/off ramps, hills, and curves change the patterns. Also, the drivers in this case were other students and faculty from the Nakanihon Automotive College, and the study doesn't say whether they knew why they were driving in circles. Again, these details could affect the outcome.
I've not been able to find any studies that test this mathematical model by documenting real-world traffic flows. But if you've got links, I'd love to see them! The idea behind this theory certainly makes sense and it would be interesting to know whether it matches up with the reality you and I experience.
Thanks, Andrew Balfour!
Google has been testing out its self-driving cars on real roads. This is still a long way from being available for you to purchase, but it's clear that it's working surprisingly well on a technological level.
You can watch some footage, recorded in the driverless cars during their test runs, in the video above. IEEE Spectrum's Erico Guizzo (who, incidentally, says he's a lot less skeptical of Google's goals after seeing this video) explains what makes the system work.
Two things seem particularly interesting about Google's approach. First, it relies on very detailed maps of the roads and terrain, something that Urmson said is essential to determine accurately where the car is. Using GPS-based techniques alone, he said, the location could be off by several meters.
The second thing is that, before sending the self-driving car on a road test, Google engineers drive along the route one or more times to gather data about the environment. When it's the autonomous vehicle's turn to drive itself, it compares the data it is acquiring to the previously recorded data, an approach that is useful to differentiate pedestrians from stationary objects like poles and mailboxes.
The video above shows the results. At one point you can see the car stopping at an intersection. After the light turns green, the car starts a left turn, but there are pedestrians crossing. No problem: It yields to the pedestrians, and even to a guy who decides to cross at the last minute.
