alt Hacker NewsThe built-in, offline mapping in my Honda uses a whole host of local-only sensors to handle these situations where GPS is intermittent. It works rather well at figuring out where the car is on the map, and when it deviates from the prescribed route.
It works in tunnels. It works in cities with tall buildings. It works on Lower Wacker Drive in Chicago.
Is there some technological limitation that precludes using this data to determine whether or not a movie can be played?
(It's not like it's new tech. It's decades-old. Honda started using it over 20 years ago.)
There's no need when OBD does just fine for this purpose.
It's also not clear what the purpose of this line of argument is. Some sensor says "car is moving". The operating system in the car/head unit is responsible for enforcing that signal, and it could ignore it equally from either OBD or some pile of gyroscopes. Where that signal comes from has nothing to do with why you will not see cars accepting custom operating systems.
