Regardless, here are three things to know about these systems.
A disturbing trend appeared in the recalls (2015) we tracked since our last newsletter. Six recalls were issued involving automated electronic systems, including safety systems directly and indirectly. And they simply got more troublesome through the course of the month.
Subaru 
the lock knob at the back of the Intelligent Key (remote control or ‘clicker’). Use the mechanical key in the driver’s door key cylinder to unlock the door.
The second key fob is the spitting image of the fob used by the Mercedes-Benz folks for years. A few old Chrysler Corp. (now FCA) vehicles use it too.
As noted, the key hole on nearly all Nissan and Infiniti models is visible at the back of the driver’s door handle, and the mechanical key can be used to unlock it. Two exceptions to this are the Nissan GT-R and the Infiniti QX80. The key hole is a bit hidden, behind the front of the driver’s door handle and a cap that must be removed.
To access the key hole, press the rear end of the driver’s door handle to lift up the front end, just as you would normally to get inside. Note the cap shown in the image (above right, A). While holding the door handle out, use the mechanical key and turn the cap counterclockwise to remove it. Once removed, the key hole is exposed and the mechanical key can at last be used to unlock the driver’s door (above right).
In the 2025, the QX80 offered a new feature — flush door handles that extend when the key fob approaches the vehicle. If the battery in the fob is weak or dead, this will not occur. Getting to the key hole is a process similar to that for the GT-R. Press the front of the door handle inward. This rotates the rear of the handle outward (right, upper). The handle can then be pulled open. Do so as far as it will go exposing the key hole beneath the back of the handle (right, lower). You can now use the mechanical key to unlock the car.
To Autopilot or Not to Autopilot, that Is the Question
Autopilot Risks
A recent accident involving a Tesla Model S with its Autopilot function engaged cost the life of the car’s driver. Since then, there have been calls to disable the function or as least rename it.
But the technology has not yet matured and it remains incumbent on motorists to remain alert and engaged. This goes for backing up with the assist of a camera and proximity sensors, changing lanes while a blind spot monitor is active, and certainly will remain the case with an autopilot engaged.
Nissan will reportedly enlist countermeasures to ensure that drivers remain alert as it rolls out its ProPilot system. A torque sensor on the steering column will determine whether a hand is in contact with the steering wheel. Moving from warning lights through beepers to system disengagement, ProPilot will require driver input, period.
We applaud this from a company that has frankly been irresponsible in its advertising of other driver assist systems.
Tesla cites the fact that in order to engage its Autopilot function, the vehicle operator must pass through and accept a warning that the system requires the driver’s attention. It is essentially the equivalent of reading a software license agreement, which we all skim at best, and is not enough.
Airline Pilots Get Confused Too
Pilot confusion with an engaged Autothrottle system was cited as the cause of the crash of Asiana Airlines flight 214 in San Francisco in July of 2013. Pilots with thousands of hours of experience and training still managed to fall on human error. Drivers will never be given training remotely equivalent to that of an airline pilot. Nissan has it right in this case.
To be completely fair, 100 people die on average every day on U.S. roadways and a single fatality after well over one million miles driven on Autopilot has everyone shouting to the rafters.
For the foreseeable future however, autonomous driving system designs need to keep the driver in his or her seat – unlike this early Tesla example from a year ago – as well as engaged in the driving process. It may defeat the spirit and purpose of autonomous operation from the driver’s perspective, but safety is the ultimate goal.
Perhaps as vehicles became more computerized, a second seat could be given the driving responsibility at times.
