Teaching autonomous vehicles to drive like (some) humans

While I love driving, I can't wait for fully autonomous vehicles. I have no doubt they'll reduce car accidents, 94 percent of which are caused by human error, leading to more than 37,000 road deaths in the U.S. last year. And if it means I can fly home at night in winter and get safely shuttled to my house an hour-plus away — and not have to endure a typical white-knuckle drive in the dark with torrential rain and blinding spray from 18-wheelers on Interstate 84 — sign me up. Autonomous technology will also take some of the stress, tedium and fatigue out of long highway drives, as I recently discovered while testing Cadillac Super Cruise. AVs are also supposed to eventually help increase traffic flow and reduce gridlock. But according to a recent Automotive News article, as the first wave of AVs are being tested on public roads, they're having the opposite effect. Part of the problem is they drive too cautiously and are programmed to strictly follow the written rules of the road rather than going with the flow of traffic. "Humans violate the rules in a safe and principled way, and the reality is that autonomous vehicles in the future may have to do the same thing if they don't want to be the source of bottlenecks," Karl Iagnemma, CEO of self-driving technology developer NuTonomy, told Automotive News. "You put a car on the road which may be driving by the letter of the law, but compared to the surrounding road users, it's acting very conservatively." I get it that, like teen drivers, AVs need a ramp up period to learn the unwritten rules of the road and that a skeptical public has to be convinced of the technology's safety. But this is where I become less of a champion on AVs, since where I live in the Pacific Northwest we already have more than our share of overly cautious human drivers. Since moving here 12 years ago, I've found it's an interesting paradox that a region famous for its strong coffee, where you'd think most drivers would be jacked up on caffeine, is also the home to annoyingly measured motorists. As an auto-journo colleague living in Seattle so aptly put it: "People in the Pacific Northwest drive as if they have nowhere to go." If you drive like me and always have somewhere to go — and usually are in a hurry to get there — it's absolutely maddening.

Cadillac recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.

Cadillac cancels its car subscription program after just two years

Cadillac is cancelling its Book by Cadillac subscription service, according to a report from the Wall Street Journal and confirmed to Autoblog by a Cadillac spokesperson. The $1,800 a month service has been in operation since early last year. The Cadillac spokesperson told us this: "Following nearly two years of service, Cadillac will temporarily pause the Book by Cadillac program effective December 1, 2018." This moves comes not too long after the decision to leave its New York City headquarters and return to Michigan. While Cadillac claims the disruption of service will be temporary, there's no defined plan to start the program back up again. The reason for the cancellation? The service ended up being more costly than Cadillac expected it to be. Owners will have 30 days from the time they're notified to turn their vehicles in. If this subscription service was your only transportation, then you better start looking for something else. The service was available in New York City, Dallas and Los Angeles. Subscribers could choose between five different Cadillacs: ATS-V, CTS-V, CT6, XT5 and Escalade. You'd be allowed up to 2,000 miles per month and 18 vehicle swaps per year through the concierge service. Cadillac would bring the car of your choice to you and take the old car away at your whimsy. The price included registration, taxes, insurance and maintenance costs. No long term commitment was necessary to sign up. This makes Cadillac one of the first manufacturers to end a nascent subscription service. If it starts back up again, expect it to look a bit different from the current program. Cadillac says it's using this experience to make strategy adjustments in the future. Whether that means a much more costly program for users, or no subscription program at all, we don't know. Plenty of other manufacturers still offer limited subscription programs in select cities. We highlighted some of the biggest ones in our vehicle subscription service guide here. It'll just be a waiting game to figure out if these modes of ownership take off going forward. For more information on Vehicle Subscription Services, check out the Complete Guide.
