This is especially directed to those in Europe who have already taken delivery. We are showing (in U.S. brochures) "delayed availability" for side assist. I assume that means that it is not arriving with A5/S5s currently being delivered in Europe as well. Has anyone been told that this feature could be added on later in a less than painful manner? Since it involves radar, I'm thinking it may be a somewhat complicated after-market install....? But it seems like a great safety feature that I'd like to have at some point if it is not available when my A5 goes into production.
