OK here is a crazy possibility, what if the model S escort team isn't just to help out the model 3 since it's a test prototype, but rather Tesla is testing advance AP (2.0 and beyond).
Sure the model 3 driver is holding the steering wheel, but there are a few reasons this could be happening :
- they are done testing
- testing requires a human to steer
- for safety the driver is required to keep his hands on the steering wheel at all times
What I believe Tesla might be testing is network AP. Tesla knows there will be hundreds of thousands of their cars on the road in the next few years, if we assume Tesla is encouraging people to use the AP, it's easy to imagine why network AP would be beneficial. Instead of you traveling on the highway with AP by yourself, your Tesla could detect another Tesla 20 yards away traveling in the same direction as you, so for convenience and safety both cars could travel single file on the same lane. Two Tesla driving with AP and sharing traffic information would be safer than a single one, plus they would probably be safer than two cars being driven by two different individuals.
I really think Tesla isn't just testing the 3, but instead Tesla is using their cars to test how well three networked AP cars could drive themselves.
Crazy? perhaps.
Cool? Totally.
