    The book can be aggravating, as in too much description, side issues, other page references etc. I went thru 46 pages of irrelavent material before I found the good section on charge timing.

    Actually that's funny, perhaps there is a B button on the Tesla?

    No need to hold the button to turn on the cruise control. Get to 28 mph or more, push the button to turn it on, tap the lever down to set the speed.

    could someone tell me exactly how to adjust the Following Distance on 2020 Prime cruise control?

    I know how to turn it on, etc, but I'd like the Following Distance to be a bit longer to not "worry" the car I'm following as much.

    Something about a "1,2,3" settings but exactly what do I press and what do I look for on what screen?

    On my car, when you turn-on CC, the follow distance is already set to the furthest out you can get - 3 bars. Unless someone went in there to adjust the system defaults, that's the way it came from the factory.
    There's an icon on the right steering wheel button cluster that depicts this; front end of car with sound picture coming out of it.
    3-bars is max follow distance; 1-bar is closest follow distance.

    1. jump into your car and place it in ready mode.
    2. toggle the cruise control system ON by pushing the button on the CC stalk
    3. find that button on the steering wheel (right button control cluster) and press it - MID should throw up a car with 3-bars in front of it. That's the max. follow distance. Hitting the button again will toggle the follow distance.
    Note: The follow distance setting will always reset to max. follow distance; every-time the CC is turned-on - Unless somebody has been messing with the car's factory default settings.

    I would think that in Bay Area traffic, you would want only 1-bar - even then you would be constantly 'cut-off', forcing the systems brakes to engage or making you run slower in traffic. 3-bars is more than 3 car lengths distance or more depending on your speed. At 65 mph, 1-bar my follow distance is usually at least 2.5 car lengths. We're not talking about mini's, we're talking about medium to large car lengths.

    Hope this helps....

    thx!
    But I'd still like about 2x as far when following on freeway, and also farther in normal driving. I like the CC radar feature in bumper to bumper but needs to do a better job of self-smoothing not going into Stop mode and needing to be restarted. In light freeway traffic where the CC radar is really nice, it still follows close enough that the car I'm following is probably thinking "we are the ONLY two cars for miles, why is he following me so close?" IMO its safer to be following another car, as a good distance, because at least you wont run into anything sitting in middle of road where it shouldn't be if you can see his taillights.

    1. you shouldn't be using it in stop-n-go traffic - It's NOT a self drive car.
    2. Adaptive CC is NEVER going to follow a lead car unsafely - If the car in front of you jerks left or right, you should also do the same. They're obviously trying to avoid something. If they run over something, there's a good chance they're going to throw it into your car.
    3. As I stated earlier, three bars is the default and you can't back-off further than that, because your reaching the limitations of the system.
    4. You won't be following anyone too closely, unless you've set your CC faster than the car your currently behind. That forces your system to slow down the car, so you don't rear-end them.o_O Either slow down or go around them. Problems solved.....
