You know, trolling or not, sounds are important. Maybe not so much as the horn, but on my older Cayenne, the constant alerts (seat belt, service, turn signal lamp out, etc.) are really annoying, like a high-pitched elevator floor alert. It drives me crazy, and now, with a rear hatch sensor bad, I get a BING and alert that the hatch is open, even though it is not. The XKR, on the other hand, has a nice, descending two-tone alert. I saw a recent documentary on BMW, and how they hire sound engineers to get the warnings and alerts to such a pleasing sound, I can speculate that the horn sound is part of that engineering. I do hope Jaguar has done the same, and made alerts and the horn grab the attention without being annoying.
