On Friday, autonomous components maker Mobileye put out a press release saying that the latest comments by Tesla on the falling-out between the two companies were “incorrect and can be refuted by the facts.”

The spat began when Tesla and Mobileye announced the end of their partnership after a fatal accident in Florida involving a Telsa owner who had been using his vehicle in semi-autonomous mode. Tesla said that the accident occurred because the car crashed into a left-turning truck, and with the glare of the sun, the car’s cameras couldn’t see the truck and didn’t brake for it.

After that, the two companies seemed to move on: in September, Tesla announced that the eighth version of its Autopilot firmware would rely more heavily on radar than it has before, despite the company having said previously that optical cameras were sufficient. Mobileye and Delphi also announced that they would be bringing a fully-autonomous system to automakers everywhere by 2020.

But neither Tesla nor Mobileye truly let the split go. On Thursday, Mobileye told Reuters that it had split with Tesla because it was “pushing the envelope in terms of safety” with Autopilot.

Tesla responded that it sufficiently educates its customers on their responsibilities as drivers when Autopilot is engaged. But a Tesla spokeswoman responded again on Thursday, saying that Mobileye learned that Tesla was developing its own sensor system for Autopilot, and the company “attempted to force Tesla to discontinue its development, pay [Mobileye] more, and use their products in future hardware.”

Mobileye then released a statement on Friday calling Tesla’s claims false. Mobileye said of the allegations that the component maker was threatened by Tesla’s own sensor development that “[Mobileye] has little knowledge of these efforts other than an awareness that Tesla had put together a small team.”

The Israel-based company wrote:

In communications dating back to May 2015 between Mobileye Chairman and Tesla's CEO, Mobileye expressed safety concerns regarding the use of Autopilot hands-free. After a subsequent face to face meeting, Tesla's CEO confirmed that activation of Autopilot would be "hands on." Despite this confirmation, Autopilot was rolled out in late 2015 with a hands-free activation mode. Mobileye has made substantial efforts since then to take more control on how this project can be steered to a proper functional safety system.

The dispute between the two companies comes as regulators are trying to figure out how to best regulate and certify autonomous systems. In July, Department of Transportation Secretary Anthony Foxx said that clarifying “pre-market approval steps” would help automakers push forward on bringing autonomy to the market.

Mobileye does seem to want to put the episode behind it, however. Noting that it will no longer comment on its fall out with Tesla, the components maker wrote:
