Could self-driving cars stop terrorist attacks?

Terrorists have taken to using a weapon that's easy to obtain and can do a lot of damage: ordinary vehicles, driven into crowds. A Department of Homeland Security-FBI bulletin from 2012 warned that "vehicle-ramming offers terrorists with limited access to explosives or weapons an opportunity to conduct a homeland attack with minimal prior training or experience." CNN recently listed nine vehicle-based terrorist attacks that have occurred within the past year, and in just in the past three months incidents in New York, Edmonton and Barcelona have claimed more than 20 lives and injured dozens after ISIS-affiliated drivers plowed into pedestrians. The deadliest so far was a Bastille Day attack in Nice, France that killed 86 people after a terrorist drove a truck into a crowd following a fireworks display. CNN also reported that "Al Qaeda's Yemeni branch encouraged its recruits in the West to use trucks as weapons," and noted that a 2010 article in the terrorist group's webzine called for deploying a truck as a "mowing machine, not to mow grass but mow down the enemies of Allah." Such attacks have been more common in Europe and other places where guns are harder to get, making vehicles violent and readily available weapons. But it's not only ISIS and Al Qaeda terrorists that have turned cars into weapons. A man with white nationalist ties drove a Dodge Challenger into a crowd of counter-protesters at the Unite the Right rally in Charlottesville, Va., in August, killing a 32-year-old woman and injuring dozens more. Some believe that autonomous vehicle technology could help stop these tragedies. "Terrorist attacks like the one in New York are a good example of why we need AVs more quickly," Caleb Watney, technology policy associate at the R Street Institute, a D.C.-based think tank, recently told the website Inverse. Dr. Junfeng Jiao, director of the Urban Information Lab at the University of Texas, told Inverse that "these tragedies may be taken into account by the makers such as Tesla and Google" when developing autonomous technology. "This is a huge opportunity for the next generation to de-weaponize cars," he added. Many vehicles already have forward collision warning with emergency autonomous braking, and a few combine it with pedestrian detection, although the latter technology typically works at speeds below 20 mph.

Chrysler recalling 31k SUVs and vans

Chrysler is issuing recalls covering roughly 31,700 vehicles worldwide due to two separate problems. In both cases the company believes that most of the affected vehicles are either still on, or in transit to, dealer lots.
One recall covers roughly 10,700 Dodge Durango, Jeep Cherokee, Grand Cherokee and Grand Cherokee SRT models from the 2014 model year built between January 16 and April 17, 2014. The SUVs need a software update for the cruise control. It's possible that when the cruise is on and the driver presses on the throttle, the acceleration could last a second after the pedal is released or two seconds for the SRT. Afterward, they return to the speed originally set by the driver.
Chrysler says it isn't aware of any accidents, injuries or even reported incidents of this happening in the real world. Also, in all cases, if the driver presses on the brake, the cruise shuts off. The automaker believes that there are about 6,100 affected SUVs in the US, 950 in Canada, 425 in Mexico and 3,200 outside of North America. The software upgrade will be ready shortly, the company says.

Performance doesn't matter anymore, it's all about the feel

We've just had a week of supercars and high-end EVs revealed. Many of them boast outrageous performance specs. There were multiple vehicles with horsepower in the four-figure range, and not just sports cars, but SUVs with 0-60 mph times under 3.5 seconds. And it's not just a rarified set of supercar builders, comparatively small tuners are also building this stuff. Going fast is easy nowadays and getting easier. So what will distinguish the greats from the wannabes? It's all about how a car feels. This may seem obvious. "Of course it matters that a car should have good steering feel and a playful chassis!" you say. "Why are you being paid for this stuff?" But a lot of automakers have missed the memo. This past week I spent some time in a BMW M4 Competition convertible, and it's a perfect example of prioritizing performance over experience. It boggles my mind how a company can create such dead and disconnected steering; the weight never changes, there's no feel whatsoever. The chassis is inflappable, but to a fault, because it doesn't feel like anything you're doing is difficult or exciting. The car is astoundingly fast and capable, but it feels less like driving a car and more like tapping in a heading on the Enterprise-D. I also happened to drive something of comparable performance that was much more enjoyable: a Mercedes-AMG GT. It was a basic model with the Stealth Edition blackout package, and even though it had a twin-turbo V8 instead of a six-cylinder, it only made 20 more horsepower. The power wasn't the big differentiator, it was (say it with me) the feel. While not the best example, the steering builds resistance as you dial in lock, giving you a better idea of what's happening up front. Pulses and vibrations come back to you as you move over bumpy pavement in corners. The chassis isn't quite as buttoned down, either, providing a little bit of body roll that tells you you're pushing it. It's also easier to feel when the car is wanting to understeer or oversteer, and how your throttle and steering inputs are affecting it. The whole thing is much more involving, exciting and fun. 2021 Mercedes-AMG GT Stealth Edition View 8 Photos That's also to say nothing of the Merc's sounds. That V8 is maybe not the best sounding engine, but its urgent churn through the opened-up exhaust gets your heart racing. It also seems like it's vibrating the whole cabin, so you feel it as much as you hear it.
