    I also noticed fast acceleration when a gap appears during stop and go traffic. It really freaked me out the first time I experienced it but I notice EAP does respond appropriately if a car in another lane cuts in. I'll try to reduce the max speed and see if it affects the sudden acceleration. I looked at the speed when this occurs and it's not really that fast. I think it feels a lot faster than it really is just because it's unexpected.

    Don't have the Model 3 yet, but our 2017 Volvo with adaptive cruise has a similar too-rapid speedup response in the situation described. I try to remember to set cruise speed down to approximate average speed of traffic, not speed limit.

    I have never driven a car with TACC that doesn`t do that.
    Never set a max velocity that`s way above what`s actually viable if you don`t want to get into close quarter combat with crossing cars.

    This is yet another reason why I refuse to pay $5000 to beta test AP. I already have to stay alert, Telsa should pay US to use AP.

    No. It regens right away because it a) sees a new vehicle ahead that is traveling slower and b) it has to obey the distance setting

    Watch the speed display, it NEVER goes faster than your preset, so clearly AP is obeying a) and b).

    When AP accelerated slowly to get back up to speed, people complained it was too slow to resume. Now, they are complaining is too fast. The car does not have the capability to discern if it is on an open road, other than the front forward facing radar. You, on the other hand, can look around. So, as AI gets better and cross talk with other cars is implemented, the car will get smarter. Right now, You will have to input some feed back and help the system, help you.

    I think one of the limitations of AP is that it lacks context / situational awareness. A human driver can assess why the lane is open and if it is safe to accelerate.

    I wonder if Tesla could moderate the initial acceleration rate if the car was just in a jam or if it detects slow traffic in neighboring lanes?

    I am pretty sure that since you are in control of the car you should have set the AP at max 40 mph if you were worried. Yes a car could pull in front of you, but it would be the same risk if you as a human driver were to speed up to 70mph thinking everyone is watching out for you.

    Once Autonomous features are ready, the car will take more info in account, such as speed of other AP drivers communicating, traffic conditions, and other learned aspects that you as a seasoned driver have realized "may" not be safe....though there are idiots who drive 60mph flying by people all the time who are creeping along.

    Right. My 10-year old car does this too, but you'd think that with all the cameras, tech, and computational power in the M3 it should be able to monitor surrounding traffic conditions and tell that there are stopped cars further ahead and not slam the throttle.

    Clearly, "Traffic Aware" is an unfortunate label. "Lane Aware CC" or "Lane Biased CC" would be be more accurate.

    What I mean is, by default, the "max" speed when TACC and AutoPilot is off is the speed of the road I'm on. So if I'm on a highway that's stopped and turn on autopilot so I can let it deal with the stop & go traffic then it will enable with my max speed set to 70 or whatever. It is, of course, on me to pay attention to that and adjust it, but I can totally see cases where you would turn it on without thinking about the fact it will accelerate heavily if the traffic you're in finally opens up and creates space.

    Perhaps it would be a useful enhancement to make TACC/AutoPilot not engage, engage differently, or beep a warning if your current speed while enabling is wildly different from the posted speed.

    I am not confused by the meaning of Traffic Aware Cruise Control or the meaning of Enhanced Auto Pilot. Neither are Full Self Driving equivalents. They are merely aids to a fully engaged driver

    The most recent firmware update has dramatically improved this condition on my car. It used to be quite jarring in its attempt to close a new gap.

    uhm, AP sets it based on the speed limit of the hwy. I understand all the "work arounds." They all make sense. dialing in the speed based on the traffic. I love AP. Don't get me wrong. I just found this situation will eventually need to get corrected such that the max speed isn't played with and it will be more aware of the situation and not just accelerate at crazy Tesla rates ... but at careful rates.

    Be sure I'll be using the work-arounds some have suggested for now!

    Yes, i too am very conservative with the set speed especially with the unpredictable drivers in our lovely city. Think Texas-sized trucks mixed in with slow drivers on Merc / Lexus and the hipsters on their Subaru :)

    i then accelerate as needed (and get the popup that Regen braking will not work during that time).

    Love EAP & Auto-steer in both stop-n-go city driving and on the open highway.. Saving graces of a car which i personally consider a bit too pretentious (mainly because it is lipstick red and has a dominant presence on the road).

    I wasn't trying to suggest that you were, just speculating out loud that people's general assumptions about TACC miss your insight.

    I should have started my first post with a +1 rather than the word "clearly"

    Well, I guess Tesla in future need to add a psychological questionnaire for each driver:
    Defensive?
    Aggressive?
    Road rage?
    Then matching with difference Autopilot personalities.

    I'm 2yrs into AP driving now (residential, fwy and traffic in both), and we can only do daily what the software provides and has progressed to.

    I'm "foot free" a lot, left hand adjusting my separation and set speed very actively (so speed-ups aren't gonna happen), while steering help happens, right hand always on da wheel. This, forces me to be aware of surroundings and my car speed/separation targets and lane centering. I'm able to disengage TACC very close to what is needed for regen to bring me to stops. In summary, I'm not complaining or suggesting any software improvements at the moment, just that YOU can be safer using what we have, rather than what we do not have.

    My adaptive cruise control does this on my non Tesla car. It can be minimized if following distance is increased but that has issues, too.
