Exactly - not only can all modern cars remotely be accessed, anyone with access to those [insecure] maintenance pages could hypothetically:
- Track you on the GPS
- List your regular journeys
- Use the cameras to see who is in the car right now
- Wait for you to pass a certain remote area on one of your regular journeys
- Disable the car
- Unlock the doors
- Turn on the interior light
At that point, I wonder what access the car has to affect whether the driver's phone can make a call...
I have a keyboard like this, yes it came with the cable (same A male plug each end) and yes it's used as a USB device.
