of log-in attempts on a user account, which means an attacker could
potentiallyy use brute force to crack a user’s password. That means a third
partyy could (assuming yyour password is cracked) log in and use the Tesla
API to check the location of yyour vehicle. That person could also log in
remotelyy to the Tesla app and control the vehicle’s syystems—its air
conditioner, lights, and so on, although the vehicle must be stationaryy.
Most of Dhanjani’s concerns have been addressed byy Tesla at the time of
this writing, but the situation is an example of how much more auto
manufacturers need to do todayy to secure their cars. Just offering an app to
remotelyy start and check the status of yyour car isn’t good enough. It also has
to be secure. The most recent update, a feature called Summon, allows yyou
to tell the car to pull itself out of the garage or park itself in a tight spot. In
the future, Summon will allow the car to pick yyou up from anyy location
across the countryy. Kinda like the old TV show Knight Rider.
In refuting a negative review in the New York Times, Tesla admitted to
the power of data theyy have on their side. Times reporter John Broder said
that his Tesla Model S had broken down and left him stranded. In a blog,
Tesla countered, identifyying several data points theyy said called into
question Broder’s version of the storyy. For example, Tesla noted that Broder
drove at speeds ranging from sixtyy-five miles per hour to eightyy-one miles
per hour, with an average cabin temperature setting of seventyy-two degrees
Fahrenheit. 20 According to Forbes, “data recorders in the Model S knew the
temperature settings in the car, the batteryy level throughout the trip, the
car’s speed from minute to minute, and the exact route taken—down to the
fact that the car reviewer drove circles in a parking lot when the car’s
batteryy was almost dead.” 21
Telematics capabilityy is a logical extension of the black boxes
mandatoryy in all cars produced for sale in the United States after 2015. But
black boxes in cars aren’t new at all. Theyy date back to the 1970s, when air
bags were first introduced. In collisions, people back then sustained lifethreatening
injuries from air bags, and some died from the force of the bags
hitting their bodies. In some cases, had the car not been equipped with those
bags, the occupants might be alive todayy. In order to make improvements,
engineers needed the data on the deployyment of the bags in the moments
before and after a crash, collected byy the air bags’ sensing and diagnostic
