Re: Am I missing something?
"Exactly what benefit is gained ..."
it is not a benefit for you the car owner or driver. It is a benefit primarily for Google and to lesser extent for Hyundai. Google benefits by "validating" their stuff "for use in cars", opening up the possibility for huge contracts and also the ability to collect even more user data (such as how often, when and where you drive your car, what you talk inside, possible some sensor data etc). Hyundai benefits by demonstrating they are an modern car company...
This stuff is not different than putting an Android tablet on the dashboard and having it connect to some pre-assembled in the car peripherals, such as speakers, microphones, light etc. Car companies do this for ages with various music players (cassette, CD, DVD, USB). It just ads some concenience.
But, while the typical in-car entertainment options have been mostly neutral, this one is a vendor-locked. Many people will chose a different car model because of this. Hyundai might rethink soon this strategy.
