During the reveal, Elon mentioned that autopilot hardware would be standard, as well as autopilot safety features. Then later that year, Tesla introduced additional Autopilot nomenclature: Enhanced Autopilot and Full Self Driving. The Model 3 product webpage still cites "Autopilot Hardware". That technically leaves open the possibility of the base Model 3 including only the hardware necessary for AP1-level Autopilot functionality - and Enhanced AP and FSD require a hardware upgrade. Maybe additional sensors or an upgraded processor or both. On the other hand, "Autopilot Hardware" is a nice concise way of saying Full Self Driving Hardware. Even so, I imagine there's quite a bit of pressure to minimize the cost of the AP sensor and processor suite on the base 3. If it only needed to support AP1 functionality, the base Model 3 could likely make do with a much cheaper processor and also would not incur the cost of the entire AP2 sensor suite. Thoughts?
