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.

The 2018 Dodge Demon sounds like nothing else on the road

The Dodge Demon seems to have a torque problem, if making too much to easily contain can be considered a problem. In order to keep all that twist under control, the Demon has a new torque reserve launch system that works all sorts of engineering black magic to build boost without overloading the rear tires and brakes. That system, combined with the sticky Nittos and the fancy new suspension, should lead to some pretty spectacular 60-foot and 1/4-mile times. The way the system works is relatively straightforward. A bypass valve on the supercharger closes, "prefilling" the blower. In order to balance revs and torque, the computer can adjust fuel flow and spark on individual cylinders. The torque reserve kicks in when Launch Mode is initiated and the engine is turning at least 1,000 rpm. The goal is to reach peak boost quicker while efficiently putting down power. The side effect is a distinct exhaust note, which Dodge admits may make it seem like the Demon is broken. That seems to be the root of the "If you know, you know" tagline that the automaker has been using since the first teaser. Those interested can even download a ringtone, which might make it seem like you have a blown-out speaker on your phone. You can get a brief taste in the latest teaser video. In addition to the new info on the Launch Mode, Dodge released a couple of new teaser images. We briefly glimpsed one of these last week. It's a shot of the Demon's performance pages. The number 757 has appeared before, and all the talk of torque leads us to conclude that this is the Demon's torque output. The number 815 was seen in a separate teaser (shown below), which we feel may be the horsepower rating. If those numbers are correct, that would mean an increase of 108 horsepower and 107 lb-ft of torque, totally reasonable numbers given all the Demon's modifications. The license plate photo is another equation or code. This one, 3.9+221=405, is just as cryptic as the others.

Watch these Dodge Demons explode on a Texas drag strip

The Dodge Challenger SRT Demon is extremely quick. It can hit 60 mph from a dead stop in less time than it takes to read this sentence thanks to its supercharged 6.2-liter V8. That engine makes up to 840 horsepower and 770 pound-feet of torque, depending on what octane is running through the fuel lines. That's a ton of power going solely to the rear wheels. So much so that Dodge developed a number of features and a new set of tires specifically for the car. In our time with the Demon, the car took abuse run after run on a drag strip without skipping a beat, but it seems some actual owners aren't quite so lucky. Just take a look at what happened to a few of these cars. You can see the whole car shake and jitter right as the whole rear explodes in front of the tree. It seems the initial shock from the launch — the most taxing bit of any drag run — is what kills the differentials. Catastrophic failure is rarely pretty, but it is neat to see the whole thing occur in slow motion. Three more cars — four stock and one modified in total — suffered similar fates. Not a great look for Dodge or SRT. According to The Drive, a private drag event in Texas drew a number of Demon owners all trying to beat NHRA NHRA Top Fuel racer Leah Pritchett's time in her personal Dodge Demon — 42 stock Demons attended along with five modified cars. While no one managed to match her 9.65-second quarter-mile run, a few owners did dip below 10 seconds. Now, there are a few of caveats we must address. First, with any modified car, you run the risk of breaking something, even with a car that's set up from stock specifically for drag strips. Even a set of tires like the Mickey Thompsons shown in the video above can have an effect on driveline components. Horsepower may be king, but it's torque that's the rear killer. All that torque sends a shock through the car. Adding even more with aftermarket parts increases the risk of something failing. The modified car was apparently pushing out about 1,000 horsepower. That said, four of the five vehicles were stock, so any extra power or torque should theoretically be a non-factor. The drag strip's surface was maintained by a company called Mass Traction. FCA used Mass Traction during the Demon's development, so that too should be a non-factor in the part's failure. It's unclear what exactly caused the failures, though The Drive reports that FCA officials are investigating the matter. Related Video: This content is hosted by a third party.
