With around than 100 million miles driven on Autopilot and 780 million miles worth of total data, Tesla has a big corpus of data at their hands — and they're willing to share it with the U.S. Department of Transportation. The announcement came at Tesla's annual shareholder's conference, where CEO Elon Musk said they've already made the offer:
On a statistical basis, we don't have any issues with them sharing that with other manufacturers. We're very sensitive about that on an individual car basis, but on a statistical basis that's an offer we've already made to the department of transport. So we want to be helpful.
Of course, whether or not the feds or other automakers will take Tesla up on the offer is another story, but with more and more car manufacturers exploring increasingly powerful autonomy solutions, if we were them we'd want as much data as we could get. It's worth noting that the data Tesla is offering to share is anonymized statistical data, so there shouldn't be any concern about the driving data of individual users making it into the hands of the government.
This isn't the first time that Tesla has offered to open their books to competitors. In 2014 Tesla de facto released their patents, offering them to anybody that wanted to use them in good faith. Of course, there's more to a Tesla car than just the patents — as the 33% premium Ford paid for one of the first Model Xs would seem to indicate. But still, even sharing anonymized data on the performance of autonomy systems will be a good thing for the industry and regulations. We just need somebody to take them up on the offer.
