Looking closer at the promised features and the available camera hardware assigned to those features i discovered that based on the current configuration reaching EAP complete is essentially IMPOSSIBLE. Here me out, lets take a took. 1) Automatic Lane Changes People forget that the current AP1 is simply a very good lane keeping and adaptive cruise control. What Elon is promising with automatic lane change is a fundamental difference. Your car actually has to be aware of the lane that its in and it has to know that changing lane would not jeopardize your destination. Its no longer a glorified lane keeping, it actually has to know where your going and how to get there. Simply seeing a free lane and taking it won't be wise because GPS isn't accurate enough to keep you within a lane or give you road changes update or what lane to stay on or exit with. You would need HD mapping (aka fleet learning), meaning a Tesla must have traversed the freeway you are on in order for EAP2 to be fully functional for that trip. Sure you can make lane changes using only Tesla Vision but that will lead to problems we already see from AP1. Decisions made with limited information lead to close calls, missed exit, wrong routes and accidents. 2) Exit Freeway and transition control back to you I believe this is the most debated topic in the autonomous field. How and when to transition control back to the driver and how long does it take for the driver to regain control. Tesla says their car will exit the freeway and then afterwards hand control back to you. There are two problems with that. EAP2 cameras configuration consists only of the redundant forward looking camera and the two rear looking cameras. The camera used for tracking traffic signs/lights and pedestrian is the Wide forward camera which is not included in EAP2. Why is this a problem? Well if you are a driver you know that most freeway exits end abruptly and quickly with a traffic light/sign intersection, sometimes a roundabout up ahead. Exit ramp most of the times are short (50 feet etc) and with sharp curves and out of no where intersection. It would be impossible for Tesla to implement a safe hand-off as they have outlined without using the wide forward camera to stop at the intersections. 3) Smart Summon - Navigate Parking Space to find you This is another feature that will require all 8 cameras in order to work as promised. In a parking lot there are cars and obstacle at every angle. While during highway driving you are only looking straight. In many parking spaces you will need your side looking cameras and main forward cameras for your car to safely navigate. Some driveways also sit adjacent of a busy road or street. Ultrasonic isn't enough, as has already been proven by the current summon system. TLDR Tesla promised Enhanced Autopilot 2 may never come to fruition till FSD is in its advanced stage, because most of the features of EAP2 ties directly to FSD. For example you can't change lanes without HD mapping of the freeway (done by fellow teslas) or take exits without main forward looking cameras to stop at intersections or navigate parking lots to find you without the aid of your side looking cameras. Sure you can perform all these maneuvers unsafely just as AP1 perform alot of maneuver unsafely today. You will end up with the same unsafe system you had before in AP1. Why? adding more features without supplemental data for that feature will be extremely unsafe and will put us owners back in the same scenario of a buggy software because of the lack of necessary information. Leading the car to make erroneous decisions leading to accidents and then the driver being blame because he isn't supper attentive. Remember the more features you have that are not implemented safely, the more attentive you have to be. Reminds me when summon was released without the dead man switch and the deficiencies in the sonar sensors made it run into obstacles. EAP2 is essentially L4 Highway that alot of companies have talked about and one being volvo, will be implementing for specific routes in 2017. But the car will be fully responsible on the highway with you watching a movie, reading newspaper or playing a game until you are a mile from your exit. That sounds alot better and safer.
