Hi, I bought a Model S last month that comes with the default autopilot (I did not pay for the Enhanced autopilot).
I am not sure what is the difference between the default autopilot and the enhanced one. Does the default autopilot also have the adaptive cruise control and lane maintenance, that “blue lane sign popping up” (this has been very helpful to reduce my commute stress). What is enhanced about enhanced autopilot that you pay extra for?
To be strictly accurate there is no such thing as "default Autopilot". EAP is the name given to differentiate the systems based on hardware 2.0 and 2.5 versions from the original AP [a.k.a. version 1] which relied on a single MobilEye forward-facing camera, a Bosch radar sensor and 12 short-range ultrasonics.
If you bought the car new then it already has the latest HW2.5 sensor suite (8x cameras, 1x Continental radar sensor, 12x longer range ultrasound sensors), but not necessarily the software activated to employ them all for ordinary driving tasks.
That is where the $5000 option for EAP comes in, which the 30-day trial let you test out.
Activated EAP principally adds traffic-aware cruise control (TACC) and Autosteer, which together are generally called Autopilot, i.e. "
the adaptive cruise control and lane maintenance" you found so destressful.
New features of EAP such as Navigate on Autopilot and Smart Summon have recently been, or will shortly be, introduced. The former somewhat automates overtaking and highway exit/interchange and the latter will use all cameras for remote parking manoeuvres, in addition to the ultrasonics.
I'm not sure what Tesla are talking about with the "
manual calibration"; maybe it means they will renew the trial on goodwill due to some defect during the first 30 days? Otherwise, without coughing up the extra chunk of dough, the car will revert to just having non-adaptive cruise control and the emergency features Tam listed, which sounds like what you *really* do not want to happen
