  • Tesla and DevOps

    That’s how someone described a Tesla recently, talking about how the software keeps changing. I had watched a few videos after I stumbled on this one:

    That got me thinking, and writing. I’ve got an editorial on this coming up, but really I was intrigued by the idea that the car would be upgraded, and not by unlocking features, but by adding them.

    I wrote before about BMW adding lots of things to the car and letting you unlock them. You could rent heated seats, for example, for a road trip, or a few months. Or rent them in your newly purchased secondhand car, when the previous owner never wanted them. That’s an interesting idea, but it’s simple. We know what’s available, and we pick from the menu of features.

    The Tesla thing is more interesting. They are upgrading the car. They have upgraded software to add more range to vehicles. They added sentry mode and dog mode. The change things, which sometimes is annoying for users when the UI moves, but it’s a neat idea.

    It’s DevOps in real time and in the real world. Not everything works, but not all changes in cars work. Plenty of mechanical designs find flaws and the last few decades, plenty of car software has had issues. I wish that more companies would adopt the upgradeable car, and make changes to improve things. Simple things, like letting me roll up windows remotely. My BMW had remote locking doors from an app, which I used when I got the airport, went inside and wasn’t sure I’d locked the car, but they stopped some of those features and turned off the wireless update (likely a security issue).

    I’m becoming more intrigued by Tesla, and I am considering one for the next car. I wouldn’t have thought that a few years ago, but for some reason the fans are convincing me.

     

  • Something Old Something New

    My neighbor had a 1978 Ford Bronco when I was growing up. He drove his kids and I around to various events, and I loved that car. The look, the removable back, the spacious interior. It was a car I’ve always wanted to own. As I’ve gotten older, however, the rough ride and lack of modern amenities have made me rethink buying an older version. I’ve become spoiled in my older age

    Ford just announced a modern version of the Bronco, bringing back the iconic truck after over two decades. What is interesting to me is that they appear to be trying to take a page from software design and customized websites by allowing lots of custom options. It appears in this look at the truck that much of the truck body can be removed and replaced with custom sections. I’m sure plenty of third party companies will offer new colors, shapes, lights, and even accessories that might truly make this car your own.

    Of course, car manufacturers want to make money, too. There are some mechanical differences with engines, transmissions, and suspension, but also a variety of settings for the drivetrain. However, different trim levels have different numbers of drivetrain settings. I wonder if there is a difference in the models or this is a software limitation (with a different physical switch). I wouldn’t be surprised if this were the case.

    I had hoped years ago that we would start seeing more customization in cars with manufacturers building a flat chassis and custom bodies, having features into software, providing interfaces, allowing for more plugins from their own and partner suppliers. Instead, it seems like we’ve gotten more and more proprietary designs, trying to lock in users rather than selling the flexibility of design. I guess that’s the way of capitalism, doing what’s best for the company rather than creating an ecosystem that might excite the consumer.

    While I know modern vehicles are built for efficiency and airflow, I think many of them start to look alike. I would hate to see every car look the same, as they have in some movies. I miss the different designs and details from the past. I would like to think that at some point we’ll see modern electric engines, controls, and features available in customized, 3D printed bodies and better software interfaces that allow us to bring back the look of the past with the best of today.

  • Favorite Cars

    Ars Technica recently wrote about their favorite cars of 2019, which is an interesting list. They get to test a lot and I read their reviews to see what they glean. I love cars, and enjoy driving different vehicles, and I’ve owned a lot in my life. I think I’ve probably owned and regularly driven 30 cars since I started driving at 16. There was even a period of a few years in my life where I traded in my car for another used one every 11 months.

    I do get to drive or ride in a decent number of cars as I travel regularly and do rent cars at times. In the past year, I managed to rent eight or nine cars last year, all different, though not very exotic ones. Still, it’s always interesting to see how manufacturers change their designs and add technology. I’ve been surprised how much I enjoyed driving around a few cars, such as the Kia Soul.

    This week, I’m wondering what you fellow data professionals out there like to drive. Are there any cars or trucks that you have look forward to getting behind the wheel of and puttering around? I’ve got a long break coming up and perhaps I’ll take a few hours and go drive something around. Give me some ideas of what you like, new or old.

    In my car history, I’ve had quite a few cars I really enjoyed. I’ve had 3 Isuzu Troopers over the years, all of which I liked. The two Suburbans (1988, 2001) I owned were both some of the vehicles I liked taking on trips. An old VW Scirocco in college was a great beach vehicle for me. My 914 and 911s are two I slightly regret letting go, but it was a good decision at the time. I enjoyed our first Prius, mostly because of the MPG when gas was US$4/gal, but it’s not a car I look forward to driving. I would like to get behind the wheel of hybrid Toyota CH-R and see what that’s like. That’s not in the US, but I could try the ICE version.

    My wife likes the Tesla, and I’ve ridden in a few. Not sure it’s the car I want, but it’s very interesting to drive. The idea of electric vehicles makes sense to me, and I expect to see more and more over time. Not sure if we’re ready for one, but we will likely look to get another vehicle in the next 2-3 years, so maybe that will be on the short list. Let me know if you think that’s a good idea.

  • Unreliable Data Sensors

    I like data, and I like cars. I think there have been some really creative and useful integrations between the two. I also think there have been a lot of gimmicks and poorly architect-ed systems, including those that insecurely allow access to vehicular systems. I even worry (very slightly) about the integrations of networks in airplanes.

    The US NTSA has said no to cameras and displays in place of side view mirrors. These are on the new Audi e-tron SUV, and would use a camera and a display on the door to show the rear view. While this certainly might help mileage, and it could allow for technology to perhaps sharpen or identify something in the display, I also worry about a couple issues. If you want to know what this looks like, here’s a review that shows this.

    First, there is the safety issue. I find backup cameras, even very new clear ones, to be harder to look at than a rear view mirror. Granted, these do show a view the mirror can’t show, but I wouldn’t want to use these when I was moving at anything above a slow 5mph backup speed. The ability to gauge distance is much harder. I would worry that I’ve both look in the wrong place, and also struggle to see the display in some weather conditions. Not to mention potential dirt, water, etc. on the camera lens. Already my backup camera is often too dirty to use.

    The second issue, and this is the bigger one for me, is that this technology isn’t anywhere near reliable enough to use in this situation. While it might work well at any point in time, I find too many issues with advanced electronics in cars that fail more often and with a much higher cost. At just over 4 years, when the warranty in my current car expired, one of the cameras in the side mirror failed. While it doesn’t appear to be hard to fix this, it’s a an expensive part (US$400). And an annoying, albeit unimportant, error on the display.

    I’m all for new technology, and I think things like the lane change warning and other tools are fantastic. ABS and traction control are lifesavers. Backup cameras have saved me or others a few times. Adjusting mirrors and other responsive improvements are fantastic, though I certainly want to ensure these devices let me know if there is any failure. Others have been less exciting, like locks that don’t operate without power.

    We know there are issues with lots of data, and we know that sensor data also needs to be checked and verified, as well as occasionally discarded. Vehicles have dramatically opened up our world and given billions abilities to access goods and services they might never otherwise see. However, there are safety issues that should override any new technology that hasn’t proven itself not only to operate at a very high reliability level, but also in a way that operators can easily adapt to using.
