In a few weeks, at WOOT (the USENIX Workshop on Offensive Technologies — an academic conference where security researchers demonstrate broken stuff), a team from the University of Michigan will be presenting a lovely paper, Green Lights Forever: Analyzing the Security of Traffic Infrastructure. It’s a short and fun read. In summary, it’s common for traffic light controllers to speak to each other over a 5.8GHz wireless channel (much like WiFi, but a dedicated frequency) with no cryptography, default usernames and passwords, and well-known and exploitable bugs. Oh boy. And what can we do with that?

tumblr_m9hum9gnmd1rsen2io1_500At yesterday’s Google I/O keynote speech, Google laid out its vision for Android Auto (reported here yesterday), which is quite similar to Apple’s CarPlay. I’ve ranted here before about Apple’s CarPlay when it was first announced and after more details came out last March. Both have the idea that your phone can hijack the screen in your car. What’s newsworthy from Google is that we have an enlarged list of vendors who are playing along. (Wired has the full list. Suffice to say that you’ll have plenty of choices if you want a car that goes both ways, if you know what I mean. Most interesting factoid: Tesla isn’t playing with either Apple or Google. Hear that? It’s the sounds of thousands of alpha-nerd Tesla owners crying out in terror.)

Today, I want to address why you should stop worrying and learn to love having your phone in charge of your car’s telematics display.

Last month, I took two business trips where I had to rent a car: one to Boston and one to Los Angeles. I rolled the Hertz dice and ended up with a Chrysler 200 in Boston and a Nissan Versa SV at LAX. Each was a 24-hour rental, but the prices were remarkably different. The Chrysler: $61.59 for one day. The Nissan? $116.31 for one day. If the street price to buy one of these cars was anything in relation to the difference in rental price, everybody would be buying the Chrysler. Boston Strong!

Last year, Apple announced iOS in the Car, which was revolutionary in that the car companies were ceding an important amount of control of the in-car experience to an external company. Now, Apple has released more details and a new name: CarPlay, which will initially work only with newer iPhone 5’s (anything with the Lightning connector) and with announced support for cars from Ferrari, Honda, Hyundai, Jaguar, Mercedes, and Volvo in 2014 and several more in 2015. Notably absent from the list are VW/Audi, Chrysler/Fiat, and Tesla.

tesla-vs-jaguar-front

A colleague and friend of mine just bought himself a Tesla Model S (the fast P85 edition). I’d been wanting to find a suitable car to compare it against, so I approached a major European car vendor’s media relations people, asking for a loaner so I could do a head-to-head comparison.

The response: “Unfortunately, Mr. Large And In Charge [not his actual name] isn’t interested in a comparison against the Tesla, Dan.” Knowing I’d never have the pull of Top Gear to get the gear I wanted in hand, I resolved that I’d do it some other way.

Recently, I received a card in the mail, inviting me to a Jaguar ALIVE Driving Experience. I’ve been to things like this before. They feed you mini-muffins, they let you tear around a mini-autocross track, you leave with a baseball cap, a mini-grin on your face, and mini-spam in your email box for months to come. I decided to invite my Tesla buddy along and see if I could get an expensive Jag in one side of my brain and compare it to the expensive Tesla in the other side of my brain. Here’s what happened.

Apple Maps displaying in a car

Apple just announced a bunch of new stuff today as part of their annual developers conference. Most TTAC readers don’t really care that iOS7 is ditching the old skeuomorphic look (fake brushed metal, fake leather, etc.) for a flat design that is damn near identical to what Google’s Android and Microsoft’s Windows 8 have been doing. However, they’ll care about this.

Pull up a chair, get some popcorn. The fireworks have been flying fast and furious. New York Times reporter John Broder wrote a piece about his press loaner Tesla running out of juice. Tesla, already smarting from the perceived slight given them by BBC’s Top Gear, decided they needed an ace up their sleeve: data logging. Chairman Elon Musk penned a response that included detailed data logs from the press car. Broder responded in general terms and then with a point-by-point response to Musk’s charges. The NYT’s public editor, Margaret Sullivan, has also chimed in with the opening of her own investigation. Notably, Musk hasn’t returned her calls. Her tentative conclusion? “I reject Mr. Musk’s central contention that Mr. Broder’s Sunday piece was faked in order to sabotage the Model S or the electric-car industry.” She also called for Tesla to release all the data they’ve got in proper machine-readable form, not just their pretty annotated graphs with the circles and the arrows and the paragraph on the back of each one.

It’s now apparently legal to have self-driving cars in California and Nevada, and this should spread across the country rapidly. One industry report predicts we’ll have them by 2019. For the purposes of this article, let’s assume that the costs will come down slowly but surely and adoption will grow quickly. Let’s jump all the way to the end point, where self-driving technology is safe, reliable, and mandatory (yes, mandatory), just like seat belts, air bags, and so forth.
