Even with this tutorial, you have to press the call button to access Cortana. With other bluetooth devices like the Blueant, everything is voice activated.

Great tutorials there!
Well I don't own a car, I just came across this tutorial when I was watching the M8 hands video by Daniel & Mark on my X1 :winktongue: .
Edit:
I like your thinking, but I don't think extra buttons is necessarily the right way. They should gave kept the core requirements of a power/lock button, volume rocker, and camera button.
The main reason we got the HTC M8 was due to lax in requirements, the android version does not have a camera button, does not have capacitive buttons. There was no R&D involved to make a new handset for windows phone, all they had to was ensure that the hardware played nicely with Windows Phone.
If MS stuck to their guns and stayed the course I doubt we would have seen any movement from the big OEMs. As all they have to do is just simply slap windows phone on their android phones, QC it and ship it out.
My proposal:
What if, a double tap of the power/lock button was used as the hardware-call for Cortana? Just like the original idea of the dedicated camera button, a double tap can be used as a quick launch of our dear assistant from a phone in standby. Not only does this negate the need for extra components, it could be implemented on all Windows Phones featuring Cortana. Phones already in the wild would only need a firmware update.
Double tap on the power / lock screen button is just a terrible idea.. as you will ended up the screen flashing on and off, to prevent this you will have to increase the threshold between button presses (same principle as increasing the time between clicks for your mouse). Plus It is just is too complicated for basic users to grasp, not everyone can quickly double press a button.
This is where passive listening would have helped, however for that to work the mic(s) need to be on all the time listening for the trigger word... just look at how the X1 launch went and the hullabaloo that ensued when people got told the kinect was always listening out for "xbox on". People didn't hear that, they just heard "the kinect is always listening".
