A6 keyless?
 

Does the A6 have keyless ignition, like the S80?

The Audi "Advanced Key" option comes with the technology package and I haven't ever received a Hertz A6 with that option.

I have a Cadillac STS with keyless ignition and I really don't see the giant advantages to the traditional ignition....

I've had an Infiniti FX45 with keyless ignition (since 2004) and it's much more convenient than taking your keys out to unlock the doors, and start the car. I can keep the key in my pocket. It's especially useful if your hands are full with groceries or, in my case, briefcase and coffee cup in the morning.

I find that pushbutton start is not as convenient as the traditional keyless twist start. You have to push the brake and press the button instead of just twisting the key slot. They added another step to start the engine instead of just one quick movement.
