Elon Musk tweeted on Friday that the electric carmaker will raise the US price of its advanced driver assistant software dubbed “Full Self Driving” to $12,000 on Jan. 17.

Tesla raised Full Self-Driving (FSD) prices to $10,000 from $8,000 in 2020. The 20% price rise comes less than two years from the previous one. Musk tweeted:

“Tesla FSD price rising to $12k on Jan 17. Just in the US.”

The CEO also added that the monthly subscription price will rise when FSD goes to wide release. He tweeted:

“FSD price will rise as we get closer to FSD production code release.”

The company has been expanding the release of a test version of its upgraded FSD software. It’s a system of driving-assistance features like automatically changing lanes and making turns. However, the features do not make the vehicles autonomous.
