It's really annoying to signal something to others that you don't intend.
I think there are a bunch of things tesla does that prevent you from being a good driver.
some examples:
- you can't flash your headlights (unless you traverse menus on the touchscreen)
- you can't set the wiper interval
- quickly turn on the defrost?
- turn on the hazard lights? (you should google it, it's funny)
newer cars go even further - no stalks, touch controls for turn signals, horn and wipers on the steering wheel
