Agree that Andrej and company are working on some great features and have made huge strides. Their latest demos look very impressive . But they will be the first to admit they are juggling the compute budget to effectively run the complex models they are working with and need to build more of in the future. From what I have seen their NN backbone is very complex and getting more complex. My feeling is they will need to make a hardware update before they can reach SAE Level 5 which would be required for a service where you dispatch driver-less cars to various locations.Latest MCU? Do you mean HW3? MCU is different from the AP hardware.
Current AP software that's in your car right now is not representative of all the work that the AP and Tesla Vision teams have been working on for the past several years. It only represents a limited subset of functions that Tesla sees as viable for public use. There's probably 2 years worth of features that you have yet to experience because it's not enabled on the current firmware yet. Things like reading parking signs, stop signs, special road markings, path prediction, bike lane detection, street intersection detection, curb detection, parking navigation, and etc...have yet to be made for public use.
My Model 3 works wonders even on the AP2.5 chip and that's only working at half the resolution and limited dynamic range.
