Following the surprise appointment of former Apple exec Bob Mansfield, the Cupertino company’s rumored autonomous car project is reportedly in big trouble.

The New York Times reports Apple is at an impasse in the pursuit of an autonomous future, unsure how to proceed. Apple has allegedly been working on for over two years.

According to the report, citing anonymous sources, Apple has laid off dozens of employees working on Titan and has even shuttered parts of the project due to lack of progress.

Apparently, the layoffs are part of a larger “reboot” of the project as the company shifts toward creating the technology necessary for an autonomous vehicle, rather than designing and producing an “Apple Car.” Apple reportedly does have vehicles in testing but there are apparently no plans to unveil a vehicle. We could hear Apple officially detail Project Titan as early as 2020.

Apple isn’t the only Silicon Valley giant working on self-driving technology. Google has been testing autonomous technology for years now, and Tesla this weekend detailed an update to its software platform that the company says is the most advanced on the road. Other big companies, such as Uber, Ford, and General Motors are also planning to release autonomous vehicles in the next five years.

Previously, Apple CEO Tim Cook hinted at Project Titan, likening the wait to “Christmas Eve.”
