I don't think it's so tough to see how this could be an economic reality.
I (and a fair percentage of the population) already have smartphones that work as wifi hot spots. (In my case it's Android but I presume all other smartphones have this capability too.) All that's needed is an in-dash internet receiver to conveniently lock in presets and search for your smartphone's wifi connection. Or perhaps via bluetooth. Very plausible -- no extra fees.
How many different smartphones are there? Android (and that alone has several different flavors), Blackberry, iPhone, etc. Each one has different connectivity protocols and interfaces. And we're not even talking about the Web-enabled non-smartphones (would that be "dumbphones"?)
Manufacturers aren't going to invest in putting in a way to "conveniently lock in presets" for EVERY variety of wireless device. Period.
If you go the Bluetooth route, that's called "tethering" - which on most cell plans is either forbidden or comes with an extra fee.
Finally "joe sixpack" (not scott - but the majority of Americans) aren't going to bother to connect their phones to their car radios when they can just turn on the one they have and get music & information.
Not so "plausible" after all.
