All Teslas come with Autopilot. It's adaptive cruise control and automatic steering that will keep you in your lane. It's awesome, and I love it.
"Enhanced" autopilot, which currently is $6000 extra, is automatic lane change, automatically taking exits, summon, and automatic parking.
The automatic lane change is nice, but it fails too often to be worth thousands of dollars. All the rest of the features are basically party tricks.
If I could have automatic lane changes for much less, I'd happily pay extra for it.
Edit: Enhanced Autopilot was $7k extra when I bought my 2nd Tesla, now it's $6k extra.
To me, design hubris is forcing someone to accept a choice-limiting or poorly documented form of automation in order to accept a more basic form. I have a Fiat 124 Spider... love it, but it has one "feature" that I absolutely hate, which is that if you hold the clutch down and brake while stopped on an uphill incline, it holds the brake for 2 seconds after you take your foot off. Presumably this is for people who don't know how to balance clutch on a hill... although the overlap between those people and the people who'd buy this car must be vanishingly low. You can disable this dumb thing - but the only way to do it is to pull the fuse that controls antilock brakes. It's infuriating.
Yes.
BTW, the automatic steering is very easy to override by just turning the wheel. When I change lanes I just turn the wheel and then turn autopilot back on.
BTW, I also had a Subaru that held the clutch on a hill. I really appreciated it in San Francisco. Personally, I don't understand the hate. I never felt like I needed it, but I remember my mom complaining about other people rolling back in a steep driveway at my preschool in the 1980s. Maybe the feature is needed for those places in the world where everyone drives stick, even the people who are clutzes?
