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 prices new XT5 from $39,990

Keen to put your deposit down for a new Cadillac XT5, but waiting to find out how much you'll need to set aside? Well the wait is over, friend, as Cadillac has announced pricing for the new crossover. US pricing starts at $38,995, which works out to $39,990 once you factor in the standard $995 destination charge. That's only $1,390 more than the now wreathless brand charged for the outgoing SRX, which the new XT5 replaces and which carried a starting price of $38,600 (delivered). It also undercuts the competition from most other luxury automakers. The BMW X3 ($40,495), Audi Q5 ($40,900), Lexus RX 350 ($42,850), and Infiniti QX70 ($45,850) each start at a higher base price than the Caddy. However the Mercedes GLE stats marginally lower at $39,875, and the Lincoln MKX goes for significantly less at $37,935 – all prices including destination charges. Of course, that starting price is just for the base model with front-wheel drive. All-wheel drive is optional on Luxury and Premium models, but comes standard on the top-spec Platinum. Step that far up the ladder, though, and you'll be looking at $63,495 (delivered).

The new luxury crossover joins Cadillac's lineup immediately following the new range-topping CT6 Sedan, as the brand enters a new phase of product growth. The XT5 is the next chapter in elevating the Cadillac brand: it is bold, distinctive and sophisticated with enhanced driving dynamics. This new crossover perfectly reflects Cadillac's positioning in the luxury automotive marketplace, de Nysschen said.

Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis
