How do you activate CC, TACC and adjust the speed setpoint?

Apologies if this was covered before...

It just hit me that 3 doesn’t have a cruise control lever, nor dedicated (hardware) buttons for CC/TACC control, beyond the autopilot position on the right stalk, which is... well, for autopilot.

How do you engage cruise control / traffic aware cruise control, then?
And how do you adjust the speed setpoint?
How do you cancel it?

Sure, obvious answer would be ”scroll wheels”.
But imagine fiddling with those while looking at the tiny speed setpoint icon on the centrally mounted screen - doesn’t quite sound like a good UI/UX. Yeah, yeah, autopilot, FSD, blah blah - that’s still at least 2 years away for a lot of people (and maybe everyone).

There has to be a smarter UI for this, i wonder how it’s gonna work.

Hopefully find out soon. I've been wondering if the shifter lever is a momentary position thing, or if it actually has 4 positions that it stays in ( R N D AP). I'm hoping the videos for the "quick start guide" will leak out or become available soon.

Maybe the same lever can be pulled toward you to increase speed and pushed away from you to decrease speed. Also maybe a small pull will change speed by 1 mph and a full pull will change it by 5 mph.

That would make sense, although there doesn't seem to be any labels on it indicating so.

Also, something occurred to me - maybe the P button isn't a P when you're in D?
Not sure if that makes sense, though. And again, no label for anything but P.

I was comparing it to the lever on the left side that flashes high beam headlights on pushes and pulls, you know, the usual way. It flashes turn signals on up and down, and windshield wipers and washers on the button on the end.

Agree. No markings other than AP.
However, P doing something else would be very confusing. I doubt that P would do anything more.

Yeah, gotcha.
But the left one actually does have the high beams indicated on it by a label (on top).



Speaking of which... The wipers control is weird too.
Shallow press for wipers, deep press for washers.
No controls for auto sensitivity, no controls for manual speed.

I bet the button for the wiper is only for a momentary wipe. Automatic wipers will use the rain sensor and sensitivity will be a setting on screen.

@orcinus you might like above.

They are treating AP as advanced cruise control. Makes sense.
Ah! Cool, thanks.
That still leaves the question of how you set the speed.
Guess it's going to have some kind of a pop-up UI on the screen + one of the wheels for that.

Hm. A bit skeptical about auto. Don't remember auto rain detection ever quite nailing the speed right more than 50% of the time. I mean, Tesla basically admits as much in S/X, since they include two auto settings right there on the stalk (plus two manual speeds).

But i guess we'll see how it performs in due time :)

Another thing that's been bugging me (don't laugh) - where do the light indicators and dashboard "lights" go?
All the stuff that shows up across the top of the binnacle screen on the S/X.

Yeah, i guess you don't *really* need them. (Until you do.)
But some of them are kinda important - i want to know if i left the wheel slip option engaged, for example, or if ABS has failed. And it's kinda nice to know if the lights are, well, you know, actually on or not (whether they're set to auto or not).

Can't wait to see where they squeeze those in on the Model 3 UI.
Top corner of the screen would be too crowded, so maybe there's gonna be a pop-up panel of some sorts that can be pulled up or whisked away when driving. Or maybe they'll show up as notifications.

Left panel of UI is more for driver assistance and providing relevant info. Hopefully it will have all we need.
I think you are right about showing notifications on UI. That seems the most logical thing for them to do.

Failures on the S and X appear as pop ups on the screen. Don't need the idiot light check bulbs period at start up, if there are no idiot lights :p

That still leaves the qutestion of how you set the speed.
On my car you can set TACC either of two ways:
1. press the accelerator to your desired speed and then press down briefly on the stalk
or
2. press down on the stalk and continue to press down. Your speed will increase by 5mph increments until you reach your desired speed and then release the stalk.

It is all very easy and takes about 10 seconds to learn. Speed is shown on the center panel UI and is easy to see. Do not overthink all of this. It will make sense once you get behind the wheel and experience the future for yourself. Then there will never be any going back.
