Tron sound

When I had my test drive last Friday my brother drove along and I wasn't even aware - too nervous, I guess - that he was shooting some videos with his phone. This is the one where the Karma is parked under a tree - it had just started raining and it was about to get worse - so we could all get in for the test drive. You can hear very well how 'Tron' sounds (the warning sound for pedestrians), although in this short video it is a bit louder than in reality. They could have also called it 'Transformer', it sounds very alien/robotic. I liked it.
