My one gripe with the car is its lack of turn-by-turn directions. To save $3,750 from the $70,000 sticker price (before $10,000 in rebates), I didn’t buy the “tech package,” which includes this feature. I assumed that since the Web browser has Google maps, I would get the same features I have on my iPhone. I was wrong. Nevertheless, I complained directly to Tesla CEO, Elon Musk. He wrote back, “The directions come from Navigon, which enables complete offline navigation, not Google. We haven’t disabled Google directions, we just don’t have the Google directions application on the car infotainment computer. At some point, we will add it, but there are many more pressing software upgrades needed before that”.
