You may not realize this, but every Tesla comes with Traffic Aware Cruise Control (TACC) and Lane Keeping (LK), whether you want it or not. You don't have to use them.
The car won't stop for stoplights or stop signs, although, if there's a car in front of you that's stopping, the Tesla will stop, too.
On highways it works Really Well, especially if you're in stop-and-go traffic. I mean, you're not going to be doing the Grand Prix on an interstate with other cars on it, but this just removes the stress of Not Running Into the Idiot Doing a Panic Stop In Front of One. (Yes, and the car can react to that likely faster than you can. Been there, done that, and watched the pick-up truck three cars back not get the memo, swerve, and side-swipe the car in front of him as well as the Jersey Barrier to the left. This was admittedly back in RADAR days, but, still.)
Hitting the turn signal when on LK kills LK, then one double-hits the shift lever to get back on LK.
Adding EAP (which one can rent for a month) adds NoA, where the car will turn off onto exit ramps and, if it's going from one interstate to another, navigate the whole way, doing its wobbly teenager act. But the car will also go from one lane to another on its own when commanded by the turn-signal lever. That might not sound like much, but it has its eyeballs fixed firmly on ye blind spots and won't go into them when there's a car there or there's one approaching rapidly. It can get fooled, but it takes work to do so. Again, not wildly useful on local roads, but for long trips, outstanding.
Have fun, and welcome to the future!
