Has anyone used the new keyless ignition system?
How well does it work?

I had a few tries with keyless ignition during my test drive of the new A6 3.2. It worked well - one button to start the car and another to stop it (both conveniently mounted on the console, just to the right of the driver). The two or three attempts I made at both worked flawlessly. I am uncertain as to the real utility of this system, but found it very neat indeed.

Ever forgot the keys in the car after locking and closing the door or trunk ? That will never happen again with that system because the system detects the key inside the car (seats/trunk) and will not allow to close the doors with the little knob. Very VERY neat feature. The start/stop is just a daily nice-to-have but the security feature is worth way more IMO.
