    Anyone who uses TAAC often can comment on if using TAAC increases the wear of brake pad vs non-TAAC? I recently activated the AP Trial Mode and noticed while on TAAC, it uses the brake often to slow down. Where as while manual driving, I would just let go of the peddle to use the regen features to slow down, resulting in minimal uses of brake.

    Is that correct.

    I see quite a bit of regen when I use TACC. Don't you see a green arc on the energy monitor when decelerating?

    Even if TACC uses the brakes a little more than careful single-pedal driving, that might be a good thing. Apparently it's possible to damage the brake system by not exercising it enough.

    From my experience, and I use it a decent amount, TACC uses brakes more often than I would, but it still uses regen a LOT. I wouldn't worry about it.

    TACC doesn't anticipate well when traffic in front of you will stop suddenly. You can anticipate better because you see 2+ cars ahead of you

    Also, it's TACC, not TAAC. Traffice Aware Cruise Control
