Owners at the Model 3 Owners Club compiled a list of over 80 different features of the Model 3 they're curious about, including questions about how the car operates (does the card unlock all the doors, where does the UI show you that your turn signals are active), physical aspects of the car (what does the tow hitch attachment look like, how much stuff can you fit in the front and rear cargo areas), and subjective details (how aggressive is the energy regeneration, does that wood trim cause glare). Ars Technica reports: So far, we've learned a few interesting facts. For instance, the windshield wipers are turned on and off by a stalk like just about every other car on the market, but changing the speed (slow/fast/intermittent) is handled by a menu on the touchscreen. The stalk also does double duty turning on the headlights, and there are no rain sensors for the wipers. The touchscreen UI really is the only way to interact with every other function, according to owners, even the rear air vents are controlled from up front (although there are USB ports in the back). Rear seat passengers also won't get seat heaters from what we gather -- unless Tesla plans to activate them in a later software update -- and the steering wheel is not heated either. The two buttons on the steering wheel do not appear to be user-configurable. Instead, the left button primarily deals with audio functions (scroll up and down for volume, left and right to change track) while the other one is for adjusting the mirrors and steering wheel position while in those menus in the UI. Additionally it appears that as of now, there's no way to tab through a different part of the UI without taking your hands off the steering wheel.
