Smart cars are hackable cars. Are the features worth the risk?

The automotive world is one of give and take. If you want hardcore performance, you sacrifice comfort; if you prioritize fuel economy and luxury, you probably won’t be king of the racetrack; and if you have a connected car, you may be vulnerable to hackers.

Cybersecurity concerns have swirled around the transportation sector for some time, but never with the same gravitas that coursed through the blogosphere last week. Chris Valasek — Director of Vehicle Security Research for the security consultancy IOActive — and Charlie Miller — a former NSA employee — were able to able to hijack a Jeep Cherokee’s Unconnect infotainment system via the car’s cellular network. Once they were in, the duo was able to send signals to the car’s computer system, manipulating the brakes, engine, and transmission with a couple laptops in a living room. All they needed was the vehicle’s IP address.

If you’re still driving your grandpa’s 1968 Oldsmobile, you probably weren’t too worried. If you own a more modern car though, one packed with wireless features and the ability to link with mobile devices, the news probably gave you some pause. And for good reason.

The modern car market demands increased functionality and inter-device communication from the factory, and there are unique security threats that come along with that. Any time a vehicle’s systems are connected to the Internet — directly or indirectly — there will be gaps in the digital armor. The fallout could be something as simple as an unresponsive radio or flashing headlights, but as we found out last week, cybercriminals can potentially access a car’s vital systems remotely, and we don’t need to explain how dangerous that is.

Any time a vehicle’s systems are connected to the Internet — directly or indirectly — there will be gaps in the digital armor.

We have yet to hear about a harmful unauthorized attack on a passenger vehicle, and clearly Valasek and Miller are not amateurs, but the vulnerabilities are clear. It’s not just Jeep vehicles either: nearly every major automaker offers an infotainment system that’s connected to the Web: Ford, Toyota, Honda, Volvo, Volkswagen, Subaru, Hyundai … you name it. Tesla’s newest vehicles can even download powertrain updates over the air, which directly affect the car’s acceleration. Is it only a matter of time before something horrible happens outside of a controlled experiment?

For answers, we turn to the carmakers themselves, and Fiat Chrysler’s initial response to the events was quite interesting. On July 22, the brand put out a press release, explaining that “some functions” had been remotely controlled, and that the automotive industry is a potential hacking target like any other. After the community began to flex its muscles, the company implemented a recall of 1.4 million vehicles, issuing USB sticks that contained a software patch to every owner alongside network-level security measures. Mailing out a truckload of thumb drives seems like an ironically insecure way to fix the problem, but a major automaker has admitted that modern cars are at risk from the attacks of cybercriminals. That’s big.

It’s impossible to say whether or not the company would have issued the recall if it weren’t for the original Wired story, but there is a clear cause and effect here — call the manufacturers out on their failings and they will address them. If we don’t? That’s a scary thought.

The U.S. government has responded as well. Senators Ed Markey (D-Mass.) and Richard Blumenthal (D-Conn.) have introduced a new bill called The Security and Privacy in Your Car Act (SPY Car Act). The legislation will direct the National Highway Traffic Safety Administration and the Federal Trade Commission to set industrywide benchmarks to protect driver safety and privacy, shining regulatory light on an issue that was largely contained within the automotive sector until now.

“Rushing to roll out the next big thing, automakers have left cars unlocked to hackers and data-trackers,” said Senator Blumenthal. “This common-sense legislation protects the public against cybercriminals who exploit exciting advances in technology like self-driving and wireless connected cars. Federal law must provide minimum standards and safeguards that keep hackers out of drivers’ private data lanes.”

It’s a start, but in the meantime, there will be hiccups. Personal safety and priceless information are all at stake here, but despite our best efforts, federal agencies, credit card machines, dating websites, and celebrity Twitter accounts are hacked every single day. It’s a constant rat race to keep up, and unfortunately for us, it’s not always the guy with the suit and tie that gets there first.

As car buyers, we crave connectivity. We lust for convenience. But are we ready to live with the consequences?

These are our picks for the most American cars ever made
1959 Cadillac Eldorado Biarritz

To celebrate the birth of our nation, the Digital Trends Cars team gathered around for the most American activity we know - a good 'ol fashioned argument. The topic of the day is what was the most American car ever made? And although we've recently looked at the most American cars sold today, this discussion was less about parts sourcing and more about what packs the most freedom vibes per mile. Each of us picked a winner, and had to defend our choice. The (dubious, entirely personal) results are below:
1959 Cadillac Eldorado Biarritz

The 1959 Cadillac Eldorado Biarritz is a pellucid reflection of mid-century American aspiration. The Eldo convertible holds a special, exalted status among all Cadillacs. Caddie’s engineers gave this model an exclusive triple-carburetor 390 cubic inch engine with 345 horsepower; a bit more than any other Cadillac of the day. Curb weight of 5,250 pounds supported by a newly developed air suspension gave this mighty road machine the ride quality of a dreamy cloud. Kitted out in flame red with a color-matched red leather interior and a fat set of whitewalls, the Eldorado was the product of an optimistic civilization at its peak. Nothing about this car looks backward, or admits any compromise. At the dawn of the space age, the Eldorado was made to transport its owner in starry splendor. This car is bigger than big, fantastically opulent, totally in your face, and utterly breathtaking. We will not see its like again.

Weighing the risks: The most dangerous cars, trucks, and SUVs in the U.S.
2017 Mitsubishi Mirage G4

Bigger may not be better, faster, or greener, but for passenger cars, larger cars are safer than smaller, according to automotive research firm iSeeCars. In its analysis of the National Highway Traffic Safety Administration (NHTSA) Fatality Analysis Reporting System (FARS) annual report, the fatal accident rate for passenger cars decreases as their size increases.

Pulling data from the 2017 FARS data tables, the most recent report, the fatal accident rates per billion vehicle miles were 2.6 for large passenger cars, 3.3 for midsize cars, 3.8 for compact cars, and 4.5 for subcompacts. The overall average rate for passenger cars was 3.3 fatalities per billion miles, significantly higher than the overall 2.3 fatalities for light-duty pickup trucks and 1.7 fatalities for SUVs. The report used data from vehicles from model years 2013 to 2017.
