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.

U.S. new-vehicle sales in 2018 rise slightly to 17.27 million [UPDATE]

DETROIT — Sales of new vehicles in the U.S. rose slightly in 2018, defying predictions and highlighting a strong economy. Automakers reported an increase of 0.3 percent over a year ago to 17.27 million vehicles. The increase came despite rising interest rates, a volatile stock market, and rising car and truck prices that pushed some buyers out of the new-vehicle market. Industry analysts and automakers said strong economic fundamentals pushed up sales and should keep them near historic highs in 2019. "Economic conditions in the U.S. are favorable and should continue to be supportive of vehicle sales at or around their current run rate," Ford Chief Economist Emily Kolinski Morris said after the company and other automakers announced their sales numbers Thursday. That auto sales remain near the 2016 record of 17.55 million is a testimonial to the strength of the economy, said Mark Zandi, chief economist at Moody's Analytics. The job market, he said, has created new employment, and wage growth has accelerated. "That's fundamental to selling anything," he said. "If there are lots of jobs and people are getting bigger paychecks, they will buy more." The unemployment rate is 3.7 percent, a 49-year low. The economy is thought to have grown close to 3 percent last year, its best performance in more than a decade. Consumers, the main driver of the economy, are spending freely. The Federal Reserve raised its key interest rate four times in 2018 but is only expected to raise it twice this year. Auto sales also were helped by low gasoline prices and rising home values, Zandi said. It all means that people are likely to keep buying new vehicles this year even as they grow more expensive. The Edmunds.com auto-pricing site estimates that the average new vehicle price hit a record $35,957 in December, about 2 percent higher than the previous year. It will be harder for automakers to keep the sales pace above 17 million because they have been enticing buyers for several years now with low-interest financing and other incentives, Zandi said. He predicts more deals in the coming year as job growth slows and credit tightens for higher-risk buyers. Edmunds, which provides content, including automotive tips and reviews, for distribution by The Associated Press, predicts that sales will drop this year to 16.9 million.

2020 Cadillac CT4-V First Drive + Video | The Cadillac of compact Cadillacs

With the launch of the 2020 Cadillac CT4, GM is pushing back into the smallest luxury sedan segment that in recent years has almost exclusively featured entries from Germany. We're pleased to see it return, and importantly, that it definitely came back prepared. The CT4’s key differentiator is its platform. Unlike the bulk of entry-level luxury sedans currently on the market, the Cadillac rides on a rear-wheel-drive platform. All-wheel drive is available throughout the lineup for those who need (or just want) four-season flexibility, but itÂ’s meant to be a convenience feature rather than a performance upgrade — the same is not true of its front-wheel-drive competitors. The CT4 ostensibly replaces the discontinued ATS, but reality is a bit murkier than that. Stop us if youÂ’ve heard this before, but the Cadillac CT4 is not entirely size-appropriate for the class. While the CT4 is aimed at the subcompact luxury sedan segment (and the CT5 at the compact), itÂ’s dimensionally a bit closer to the likes of the Mercedes C-Class than it is the A-Class. This gives Caddy a bit of an advantage, but itÂ’s nothing we havenÂ’t seen from GMÂ’s luxury arm before. Cadillac has chosen instead to target the segment based on price, which is a win for consumers in a way, as you can get a little bit more bang for your buck if theyÂ’re willing to take a chance on the underdog. Cadillac is offering its new small sedan in three states of tune. The base (“Luxury”) model boasts a 2.0-liter engine good for 237 horsepower and 258 pound-feet of torque. The Premium Luxury and CT4-V models get the 2.7-liter — which is still a four-cylinder — that makes 310 hp and 350 lb-ft of torque in its base tune and 325 hp and 380 lb-ft in the CT4-V. All three variants make use of GMÂ’s active fuel management tech which allows them to run on just two cylinders to conserve fuel while cruising. Yes, you read that correctly. The CT4-V boasts just 325 hp, which may seem like a pittance considering the outrageously powerful V models of CadillacÂ’s past, but GMÂ’s luxury arm has decided to re-jigger its performance hierarchy by eliminating “V-Sport” entirely, shifting “V” down to fill that role, and introducing a series of new range-topping performance models dubbed “Blackwing.” In that context, the CT4-V may seem like an also-ran, but consider the company it keeps.
