I keep reading on these forums about how bad the Tesla navigation is and I'm wondering how bad it really is. I'm asking this question in the ANZ section as we often get the rougher end of the pineapple compared with the US and Europe. I have an Italian car with some off-the-shelf navigation system that pretty much sucks. It sometimes doesn't know where I am and offers some bizarre suggestions about how to get to places, particularly in the city. But that's not why people buy that particular car so it's OK. Marge has a Lexus with a pretty incredible navigation system. It's probably not quite as good as, say, using Google or Apple maps, but it knows about traffic snarls, accidents, road closures, etc, and reacts to changes in information and suggests alternate routes while driving. It looks good too. So, how bad is the Tesla NAV really?
