Siri button on steering wheel?

I came across this:
"Forstall also mentioned a new feature called Eyes Free. He said Apple is working together with car manufacturers to integrate a button for triggering Siri from your steering wheel; among the companies looking to integrate that feature in the next twelve months are GM, BMW, Mercedes, Land Rover, Jaguar, Audi, Toyota, Chrysler, and Honda."

And I am just wondering if there will be some sw update, so it will be available to existing cars...

That's nothing new, I have had it for the last 10 years.

It's called "my wife"

:DDD

Hopefully it will come with the next software update.

Hmm that would be very helpful
