In terms of news, on May 21, market media reported that Tesla announced that the supervisory version of FSD has been opened for use in 10 countries or regions, including China. Affected by this news, Hong Kong stocks related to intelligent driving surged during the session. CITIC Securities analyzed that although there is uncertainty regarding the current global L3 access and Robotaxi (autonomous ride-hailing) policies, as intelligent driving technology advances to L3/L4 and companies increase their investments, the trend of policy access shifting from operational testing to large-scale commercialization is clear. Major cities in the United States, the Middle East, and China are expected to be the first to establish an economic model. Huatai Securities pointed out that JOYSON ELECTRONICS' intelligent driving business is progressing smoothly, and the company has formed a complete product matrix covering L2+ to L4 levels. Domestically, the company has secured several core projects for both independent and joint venture brands, with the cooperation project for L3 intelligent driving with a leading domestic independent brand expected to enter mass production as early as mid-year. Internationally, the company is accelerating breakthroughs in the Southeast Asian, European, and North American markets, with ongoing deepening cooperation with Vietnamese new energy vehicle company VinFast. Related intelligent driving domain control projects are expected to enter a concentrated mass production phase this year, with further volume growth anticipated. Currently, the company has a sufficient reserve of intelligent driving projects under research, and as subsequent orders gradually convert, the pace of revenue release is expected to accelerate significantly ### Related Stocks - [TSL.US](https://longbridge.com/en/quote/TSL.US.md) - [600699.CN](https://longbridge.com/en/quote/600699.CN.md) - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) - [TSLL.US](https://longbridge.com/en/quote/TSLL.US.md) - [TSLG.US](https://longbridge.com/en/quote/TSLG.US.md) - [TESL.US](https://longbridge.com/en/quote/TESL.US.md) - [TSLR.US](https://longbridge.com/en/quote/TSLR.US.md) - [TSLT.US](https://longbridge.com/en/quote/TSLT.US.md) - [00699.HK](https://longbridge.com/en/quote/00699.HK.md) - [600030.CN](https://longbridge.com/en/quote/600030.CN.md) - [06030.HK](https://longbridge.com/en/quote/06030.HK.md) - [601688.CN](https://longbridge.com/en/quote/601688.CN.md) - [06886.HK](https://longbridge.com/en/quote/06886.HK.md) - [VFS.US](https://longbridge.com/en/quote/VFS.US.md) - [HTSC.UK](https://longbridge.com/en/quote/HTSC.UK.md) - [VFSWW.US](https://longbridge.com/en/quote/VFSWW.US.md) ## Related News & Research - [Tesla FSD v14.3.3 adds faster ASS and new FSD Stats [2026.14.6.6]](https://longbridge.com/en/news/286782990.md) - [Tesla now forces drivers to give feedback when intervening on ‘Full Self-Driving’](https://longbridge.com/en/news/286479354.md) - [Chinese firm Xpeng builds driverless cabs, challenging Tesla’s FSD software](https://longbridge.com/en/news/286846989.md) - [Stellantis Plans $70 Billion Comeback With LFP Batteries And A Tesla FSD Challenger](https://longbridge.com/en/news/287255877.md) - [Tesla has a possible fix for chaotic charging lines](https://longbridge.com/en/news/286133106.md)
