Re: marketers?
In US, VA in particular each car dealer has a "tag" book. In theory helps speed taking trade-ins only from registered owner. Of not available to individual owners. Reasons: Money and Convenience.

Actually has happened more than once--a Canadians has particular problems with conversions from metric fueling and English gauges. One in the middle of Atlantic at 40,000 feet. That was the saving grace--they coasted from flight altitude 120 miles (or was it 120 Km?) to a successful really dead stick landing in Azores.
The shootdown of Korea Air Flight 007 by Soviet aircraft had a likely cause that the starting reference was improperly keyed--fat fingered into its INS. The cure is to build up a data base of known starting lat/long/alt that is protected by check digits. Easy to add to printed Jepp charts, but they are moving to complete electronic tablets, etc.
Then, have to deal with securing how to get to the "right" starting page.
Nosing down generally picks up speed both downward and forward, recognized by noted Brit AC designer I. Newton. Pilots slow down AC by applying back pressure. Once AC is actually on ground (by checking the WoW switches (aka "Squat switches), then slow down with hard braking, forward stick, flaps up, and if configured deploy slats and tail parachute.
GPS data in wet Wales becomes unreliable because of change in Speed of Light as encountered on the different paths from the 4 or more satellites needed. And you may have to up the computation rate of the GPS package to deal with an AC moving at 120+ FPS (30MPH=44 FPS.)
Another design feature was that you could hang a failed/repaired engine on a hard point on the wing of a 747. Couldn't change it in mid-flight but it ensured being able to get a dodgy bird to the maintenance facility location. Actually rode a TWA 747 from Heathrow to JFK in about 1977.
Into which we will shovel the reprogrammed "legacy" code converted from the old legacy (mainframes anyone?) languages running on the newest versions of LINUX, and which will be tested to work out all the problems caused by lack of documentation of that legacy. Been done dozens of times before (really) at about 1+ manhour per instruction. More if it is real-time.
Hire one of the cloud providers to monitor that several hundred boxes running the infrastructure code they understand, and a few greybeards to look-see the macro operations..
On the other side of the pond, a security researcher is in BEEG trouble for either patching into a commercial airliner's engine controller system from his seat back and making the aircraft yaw, or he just made up that story and tweeted it, and got kicked off the flight and then corralled by the FBI with some major league criminal charges. http://www.theregister.co.uk/2015/05/19/airplane_hacking_panic_why_its_a_surely_a_storm_in_a_teacup/
There is substantial dust-up as to whether it could have happened, even if he didn't actually do it on a real flight.
And the use of the CRM 114 discriminator absolutely prevents any errors and ensures General Ripper's commands are adhered to. Does the ARINC 629 provide the same protection.
Where do they get the juice to power the ailerons, rudder and elevators when they lose the main AND APUs--say because they run out of fuel, like a couple of Canadian planes did in the past. One coasted for 80 miles over the Atlantic and luckily has an island in their path.
And earlier this year the FCC was forced, after a lot of testing, to deny use of the frequencies near the GPS band for a competitive cellular telephone service. It really chafed them because they had previously granted the frequencies, and the proiver is really irate, in the billions of dollars level.
