That's quickly becoming the main point of differentiation in most reviews since cars in a certain class have become more or less the same performance wise.
Speaking from the perspective of just wrapping up the car buying process. All of the reviews had just as many, if not more words devoted to the infotainment experience as to the driving experience.
Here I am thinking Bluetooth is peak feature so I can play my music while carving canyons and reviewers are taking off points because the touch screen isn't colorful enough or something.
Or the Bluetooth connection works, but does random things you can't change. The last rental car I had, upon connection, forced Spotify to re-open and start playing the last playlist. Even if Spotify was closed.
Some entertaining solutions I found online include a playlist that includes only silent tracks and switching to that playlist before you turn off the car, or canceling Spotify Premium so you can no longer download/cache songs, giving you enough time to mute before Spotify's cloud can stream the song to the car.
