As someone who has studied a lot about UI design and human psychology (I have a degree in psychology and neuroscience), there are a significant number of design faux pas in the Tesla UI design. There is tons of research that documents how our visual acuity, attention, visual processing, and motor reflexes all work in tandem. There are clear ways that innate biological functions dictate how we take in information and process it in decision based operations like turning on wipers or looking for the artist of a song on a screen as we drive. It seems like Tesla is focused on how the interface looks more than how easy it is to operate. They really should have someone with experience in human centered computing who can help them with designing the UI with human psychology in mind. Much of the time we are interacting with the screen, we are hurtling through space at high velocity with moving objects all around us. The UI should be as simple and easy to use as it could be with the most pertinent information readily available in milliseconds. Not everything in Tesla's UI is like this.
