The following submission statement was provided by /u/nastratin:

In California, every driver involved in the testing of autonomous technology has to be registered. Every vehicle involved in testing has to be registered as well with the DMV and has to have a special permit to drive on public roads.

Thanks to those regulations, we now know that Apple’s autonomous driving dream has reached impressive size. The company increased the number of test drivers to 201 while its fleet of test vehicles remains at 67.

It is clear that over the years Project Titan evolved into three separate programs. While the autonomous car has been on and off the drawing board many times over, autonomous driving technology took its own course. Apple can easily leverage its expertise in hardware and software to develop advanced self-driving tech and it aims to achieve it before its rivals.
