Do you have a source for this? Because everything I've read to date on the Model 3 indicates that it will have Autopilot.
Although, like the Model S/X, you will probably have to pay for the features to be enabled (the hardware is still present).
This is not a Level 4 Autonomous car[1], as they've made clear repeatedly and why they use the term Autopilot.
[1] https://en.wikipedia.org/wiki/Autonomous_car#Classification
A level 3 or 4 autonomous car is a true autopilot.
Tesla is level 2.
The Pilot is always required to monitor the systems and be able to take control - so the analogy to a Level 2 autonomy car system like Tesla's Autopilot is quite correct.
Anyway, my point is if you keep talking about Tesla's lack of autopilot - regardless of the case - you're going to just confuse most people, because clearly they do have that.
If you want to refer to Level 4 systems, perhaps 'driverless' or 'self driving' are better terms to use.
