My wife can do away with most of that stuff except CarPlay, but the phone is essentially that. You can also add a wireless CarPlay monitor or add a stereo later to add CarPlay.
My wife hates all the driving tech both cars we own have, and the only thing she uses is the Parking Hold. I believe...
I also went to see the Slate. I was impressed and more importantly the wife was.
We also saw the Telo truck cruising the parking lot, one ugly “truck” Wife said “hell no” when asked if she would drive the Telo. 🤣
