Just returned from a week driving trip in Germany. Originally planned on European delivery of the Porsche Panamera hybrid. Glad I cancelled since the hybrid production has been delayed, otherwise I would have been without a car. I ended up renting a Audi S7- got up to 265kph. Anyways stumbled upon the adaptive cruise control and was quite impressed with it, especially in stop and go traffic. I tried it on the Giulia this morning and it worked adequately. The Audi's felt a little more advanced. Anyways my question is when the car slows down or brakes, does the rear brake lights turn on. If that is not the case I would be worried about the guy behind me rear ending me.
