To your question about the thumbwheels on the Model 3, as you mentioned, the intent is that they change in function a little bit based on what active features are running. The default left button controls the radio to some degree but if you want to mess with treble, bass, concert hall settings, those are done on the pad. The voice command library is still evolving and it's great for nav or radio but to say "turn up the fan" or "open the glovebox", it won't and that requires taking your hand off the steering wheel and two touches to the screen. As I mentioned earlier, you can basically ignore the screen for days and not impact the driving experience. The TACC and Autopilot are initialized thru the stalk and then you adjust speed with the right thumbwheel. I will have to play around with them some more to see what other functions they can do as well as the voice commands to open up settings and such. The more you drive it, the more you see the beginning of the FSD concept with all the autonomy along with safety and convenience features. I just downloaded the latest upgrade which includes a lot of additional safety features, and convenience settings as well as the summon feature. Supposedly there's another big upgrade coming this month to add more autonomy to the EAP.The first request I had was to turn creep off if available. There is a creep setting and it was disabled. I estimate the regen wasn't as strong as the Bolt, and the TM3 would 'coast' under 10MPH, (perhaps a little less than 10MPH) with no regen available. So one absolutely has to use the brake pedal to come to a complete stop. Again, my review is extremely weighted as I have become like that dishwasher detergent commercial where the kid says "...what does the dishwasher dooo?" Getting to comfortable with Bolt "L" driving and I'll be saying "...what does the brake pedal doooo?"
The steering wheel has 2 thumb scroll wheels, that work in conjunction with the center tablet. The driver can adjust the side mirrors, or adjust the steering wheel, or click the AP speed up/down in 5MPH increments, and probably a lot of other stuff. I would like the TM3 owners here to confirm this; you need to interact with the tablet manually to get to the proper screen for these thumb scroll functions to do the thing you want them to do? Can the driver somehow use the thumb scroll to interact with the tablet, and change screens without having to physically touch the tablet?
Otherwise, it would seem that the driver would need a F-14 Tomcat-like Radar Systems Officer in the passenger seat to help manage administration of the car.
It's amazing what aesthetic design can do. The Bolt is seems to be only 5 or 6" shorter, but apparently its 21" shorter. The TM3 is just 3" wider. When I see the TM3 on the street, it seems much wider. But when side-by-side, it's like some optical illusion. Again, visually, the Bolt looks to have a stubby front hood, whereas the TM3's is long and sleek. but from the respective windshield to the most forward tip of the cars, it's not that much difference. perhaps 3-4"?
That 3" width is very evident in the interior of the TM3. The center console arm rest is visibly wider, add that the TM3 seats the passengers in much more of a reclining position (as low slung sedans do). So the driver and passenger can share the arm rest without elbows touching. I imagine this is very comfortable for long distance driving. Whereas the Bolt center arm rest is a one-person arm rest only, as the seating is more upright.
