I thought that with the recent article about AP 2.0 hardware possibly being out in the wild now or soon, it would be a good time to let Tesla know that many of us would be severely interested in a hardware retrofit package. Of course, we still don't know what the additional features or improvements will be exactly, but I think we can all agree it will be better and impressive. Currently, I would imagine such a retrofit could affect nearly 100k cars so this wouldn't exactly be a niche market for Tesla. Keep in mind, we should not expect Tesla to offer something that isn't covering their costs 100% (labor/parts/R&D for retrofit). Unlike pre-AP cars, the cars with current AP already have the most crucial interfaces setup (throttle, brake, steering). You'd simply be adding more sensors for the processing of those commands to control the inputs. In closing, I completely understand that the hardware requirements could be expensive and numerous. By my estimation, we have at least a couple more cameras (same area), rear camera, different windshield, and added radar units (may require additional wiring harnesses). But we'd still like to know the cost and the feasibility so that it can be the owner's choice. One of the huge concerns for owners is product obsolescence. And having to sell a car with outdated technology with no chance of changing will affect resale values tremendously. By at least offering an upgrade path, you help stabilize those resale values to some extent.
