On January 19, news emerged that Tesla CEO Elon Musk revealed last week that, commencing February 14 of this year, Tesla's Full Self-Driving (FSD) system will solely be accessible via a subscription service, and the option for one-time buyouts will no longer be available. Previously, Tesla started offering its autonomous driving system for sale at the price of $5,000 as early as the end of 2016. Over time, it has increased the price multiple times, bringing it to the current rate of $8,000. In 2021, Tesla also rolled out a monthly subscription plan. This adjustment represents a substantial transformation for Tesla.

### Explanation of Optimization 1. **Sentence Structure**: - “it was reported that” is a relatively common but somewhat passive - sounding phrase. “news emerged that” is more vivid and active, making the statement more engaging. - “announced last week that starting from February 14 this year” is a bit long - winded. “revealed last week that, commencing February 14 of this year” is more concise and has a more formal tone. - “with no more support for one - time buyouts” is changed to “and the option for one - time buyouts will no longer be available” for better clarity and a more natural flow. 2. **Cultural Background and English Habits**: - Using “roll out” instead of “introduce” for the monthly subscription plan gives a more business - like and dynamic feel, which is in line with the context of a company launching a new service. - “marks a significant shift” is replaced with “represents a substantial transformation”. “Represents” is a more commonly used verb in formal business and technology - related writing, and “substantial transformation” is a more powerful and descriptive phrase than “significant shift”.
