Driving along city streets with TACC enabled, when a car makes a turn a couple of hundred feet in front of me, crossing my path, it seems that my Model 3 doesn't even apply the brakes until the turning car is already out of my path. Then it abruptly slows down and I have to press on the accelerator to speed back up.
I would think the computer would react more quickly than that. Of course, I can see the car preparing to turn even before it enters my lane, and I can judge its motion and inertia and clearly see that it will be out of the way well before I get to it, but with a microprocessor and radar and/or front camera, it just seems surprising that the Model 3 is so slow to react.
NOTE: For those of you preparing to admonish me to read the manual, and warn me that TACC is only for highway use, I am well aware of the "official" position from Tesla. I also know that when I got my car over a year ago EAP only worked on limited access highways, but at some point last year it suddenly started working on city streets. To me it's obvious that Tesla wants to collect data from city driving and though they can't officially endorse it, I am helping them by using it anywhere it will engage.
