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 CT6 V-Sport wants to take prisoners with 550-hp 4.2L TT V8

With the refresh of the Cadillac CT6 for 2019, Cadillac welcomes the first CT6 V-Sport as well as a new trim strategy. The changes at the front for the CT6 lineup don't appear substantial viewed head-on, one needs a side view to appreciate the greater three-dimensionality. Thinner headlights and a thinner bumper above a slightly larger lower front intake emphasize the mesh grille, and the vertical LED DRLs make more dramatic statements thanks to those narrower headlights. By angling the main units back toward the rear of the sedan, the CT6 now has a certified, sculpted snout. The rework appears to add substantial overhang, but overall length only increases by a tenth of an inch, to 204.1 inches. What's under the V-Sport's probing hood is just as interesting as the redesign and the sporting thrust: A clean-sheet design of a 4.2-liter DOHC twin-turbo V8. In the V-Sport, the engine produces 550 horsepower and a Bentley-esque 627 pound-feet of torque. As an optional engine elsewhere in the CT6 range, the same engine produces 500 hp and 553 lb-ft. The displacement, specs, plus the fact that "each engine will be hand-built at the Performance Build Center in Bowling Green, Kentucky" indicate this was one of the rumored powerplants for the mid-engine Corvette. The coming sports car was tipped to get a 4.2-liter and 5.5-liter DOHC twin-turbo V8. Based on the position of the turbos in this engine vs. their positions in the previous CAD drawings, we assume the drawings represented the 5.5-liter. (Note: Cadillac said Corvette will not get the new 4.2-liter twin-turbo engine.) The 4.2-liter item features an aluminum block, heads, and pistons, direct injection with a 9.8:1 compression ratio, cylinder deactivation, cylinder oil jets, and a variable-pressure oil system. The twin-scroll turbochargers capable of 20 pounds of boost sit in the 90-degree vee, working alongside twin water-to-air intercoolers, twin throttle bodies, and twin electric wastegates. Cadillac says 90 percent of torque arrives at 2,000 rpm and loiters through 5,200 rpm. Power gets sent through GM's 10L90 ten-speed automatic transmission and on to the standard all-wheel-drive system. Cadillac didn't list 0-to-60-mph times in its press release, but engineers have track-worthy alacrity in mind for the CT6 V-Sport.

Al Capone’s bulletproof 1928 Cadillac Town Sedan is back on the market

It turns out that infamous mob boss Al Capone played an early role in the development of the modern armored executive car, and now there’s another chance to own his bulletproof 1928 Cadillac Town Sedan, which is being offered by Celebrity Cars of Las Vegas for a cool $1 million. It was last seen netting $341,000 at auction by RM SothebyÂ’s in 2012 and does not appear to have undergone significant restoration since then, raising the question of why its value has jumped nearly threefold. Painted green with a black roof, fenders and bumpers, the car is said to be the earliest surviving bulletproof vehicle, with nearly inch-thick glass and once lined (but no longer; read on) with nearly 3,000 pounds of asbestos-wrapped steel armor plating. It features a rear window rigged to drop quickly, so the tough guys in the rear seats could fire on any pursuers. Heavy spring lifts operated the side windows, which were also rigged to raise higher than usual to reveal a circular cutout big enough for the muzzle of a machine gun. In this case, the factory specs may be the least interesting part of the car, though it is undeniably a looker. It features a Series 341-A, 90-bhp, 341 cubic-inch L-head V8 engine mated to a three-speed manual, with a beam front axle and full-floating rear axle with semi-elliptical leaf springs and four-wheel mechanical drum brakes. It has only 1,111 miles on the odometer, having spent much of its history in museums or on display at carnivals and amusement parks. ItÂ’s believed to have flown under the fedsÂ’ radar in a Chicago garage owned by Emil Denemark, a known mafia associate and South Side Cadillac dealer who was related to Capone by marriage, when the mob boss began his slide into legal troubles leading up to his eventual felony conviction and jail time. In 2008, an elderly man named Richard “Cappy” Capstran told a friend that he had once helped his father install armor plating on a Cadillac owned by Al Capone. His father, Ernest Capstran, had repaired another of CaponeÂ’s vehicles and earned the mobsterÂ’s business fortifying the brand-new Cadillac. “My dad said, ‘We donÂ’t do that kind of work here.Â’ And they (CaponeÂ’s men) said, ‘You do now,’” Richard Capstran recalled in a recorded interview, per SothebyÂ’s. CaponeÂ’s associates reportedly also backed the car into the shop so no one could see what kind of work was being done to it.
