One-Touch Transfer as Trust Chain Extension: Another Angle for Phone Makers Entering EVs

Last week in Hangzhou, I chatted with a friend working on connected cars at Great Wall Motors. He said his biggest headache isn't Bluetooth pairing success rates, but users being confused about the difference between "connecting phone to car system" and "controlling car system via phone." The former is just a pipe; the latter involves permissions. Today's joint release of "Car System Tap-to-Transfer" by vivo and Great Wall looks like a minor feature, but it actually pushes the trust chain between phones and cars one step further.
