Yeah, IMO, the car is really the one area where cellphone makers have been slow to adapt to what the market really needs.
EG. Android developed a simplified "home screen" that can be configured to display whenever the phone detects it's attached to a car kit. Great idea that the iPhone hasn't even begun to address, to date. The Android implementation is still weak though, IMO. I know with my Sprint HTC Evo 4G phone, for example, it never auto-switches in my Jeep because apparently, it's not enough for it to physically pair up to my car stereo via bluetooth. It wants to see some sort of *physical* cable connection that lets it know a car kit is attached, or at least, the ID of a known "car kit" device its programmed to look for?
MUCH more could be done though. I know I'd like to see "out of the box" solutions that detect you're connected to a car stereo and therefore, automatically switch SMS texting to a mode where incoming texts are read to you, and voice recognition is used to compose replies. (On vehicles with a full-screen touchscreen type stereo, it'd be slick if they could even display an incoming MMS photo or video on the car's screen, too.)
Oh what the industry can do when it's not limited to the accomplishments of one corporation. (Even one as big as Apple)
