the article talks about how people are saying that tesla, which makes electric cars, is a bad investment. One person named gordon johnson thinks that tesla's business of making robotaxis, which are cars that drive themselves, is not working because of a technology problem. He also thinks that elon musk, the person who started tesla, is hiding problems with the company. Read from source...

1. The title itself creates negative emotions and instills a sense of distrust in the reader. Using terms such as "Smoke and Mirrors" seems to be a manipulation tactic to discredit Musk's efforts, without providing concrete evidence.

2. The argument that Tesla's margins are declining seems to be a valid point, although the statement that Musk is hiding this fact through 'smoke and mirrors' appears to be based on personal opinion and might be seen as a stretch by some.

3. In the argument about Tesla's robotaxi business, the statement that Tesla lacks lidar technology, thereby making full self-driving feasible, is a factual inaccuracy. Tesla has been working on its full self-driving technology for a while, using cameras, radar, ultrasonic sensors, GPS and IMU for mapping and navigation.

4. The claim that Tesla's car sales growth has declined is a potentially valid concern, but again, calling it 'smoke and mirrors' seems to be an exaggeration, and appears to be based on personal opinion rather than verifiable data.

Overall, the article's tone and arguments appear to be excessively critical, and might be seen as overly negative by some. The language used could also be seen as inflammatory, and designed to create a negative reaction in the reader. It would be advisable to approach the article with a critical eye and to verify any facts or data cited through independent sources.

Bearish

The article is bearish on Tesla, with an analyst arguing that the company's robotaxi business has fundamental technology issues, and that Musk is promoting 'smoke and mirrors'. The author believes that Tesla's share price will eventually fall below $30 a share due to declining margins and a lack of lidar technology for robotaxis.

Tesla's shares are overvalued, and Elon Musk's promotion of the company's robotaxi business is a 'smoke and mirrors' strategy to hide declining margins. Additionally, Tesla's robotaxi technology lacks the necessary lidar technology for full self-driving capabilities. Therefore, investing in Tesla may be risky due to its overvalued stock and potential technological limitations. However, it is essential to consider other factors such as market trends, company performance, and economic indicators before making any investment decisions.
