Tesla will once again raise the price on its misleadingly named Full Self-Driving feature, company CEO Elon Musk tweeted Friday. Beginning Jan. 17, the Full Self-Driving option will cost $12,000 -- a $2,000 increase over the current price.

This isn't the first time Tesla raised the price on its Full Self-Driving function that -- and we cannot stress this enough -- is not a fully self-driving technology. (There are no self-driving cars currently for sale.) In Nov. 2020, the price for FSD rose from $8,000 to $10,000.

Musk also tweeted that the price for Full Self-Driving will rise again as the technology gets closer to production.

Right now, selecting the FSD option gets you Tesla's Autopilot driver-assistance suite, which includes automatic lane changes, automatic parking, steering assist on limited highways, the Summon function and more. If you purchase the FSD option, the car gets added hardware that will enable fully self-driving capabilities if and when those ever become legal for road use. 

We've found the Autopilot system to be hit or miss on long-term Tesla Model Y crossover, largely due to a constant phantom braking problem. Tesla's made a number of over-the-air updates to this technology over time, and says it is constantly tweaking and improving these driver-assistance features.

Tesla does not operate a public relations department and is therefore unable to comment on Musk's tweet.
