Alright, let's imagine you have a lemonade stand. This is kind of like how Rivian makes and sells cars.

1. **Deliveries**: Every time you sell a cup of lemonade (or Rivian sells a car), that's a delivery.
- In the summer (third quarter), you sold 10,000 cups (Rivian delivered 10,000 cars).

2. **Gross loss per unit delivered**: This is like how much money you lose on each cup of lemonade you sell.
- Last summer, you lost $39 on each cup (Rivian lost $39,000 on each car). In the spring (second quarter), you only lost $32 per cup.

So, Rivian made fewer cars in the summer compared to the spring, and they lost more money on each one. This is why their 'gross loss per unit delivered' went up. Read from source...

Based on the provided text for Rivian Automotive's third quarter report, here are some potential criticisms and aspects you could discuss:

1. **Inconsistencies**:
- The company reported a gross loss per unit delivered of $39,130 in Q3, but in October, it stated that it is on track to turn a gross profit in the fourth quarter.
- Rivian also reduced its annual production forecast by up to 18% due to component shortages, yet reaffirmed its 2024 delivery outlook.

2. **Bias**:
- The article doesn't provide much context or comparison with other EV manufacturers, which might give a more accurate picture of Rivian's current standing in the market.
- It might be seen as biased by focusing too much on Rivian's losses and setbacks without highlighting any improvements or positive developments.

3. **Rational Arguments**:
- The article doesn't delve into why Rivian's gross loss per unit delivered increased, making it harder for readers to understand the reasons behind this change.
- It could benefit from more detailed analysis of Rivian's current situation and projections, rather than just reporting numbers.
- A counter argument could be that Rivian is still a relatively new company in the EV market and such teething issues are to be expected.

4. **Emotional Behavior**:
- Some readers might interpret the article as causing panic or worry due to its focus on losses and delays, especially for those invested in Rivian stock.
- However, it could also be seen as providing an honest and realistic assessment of the company's current state, allowing investors to make informed decisions.

5. **Lack of Analysis**:
- The article provides numbers but doesn't analyze them in depth or compare them with industry averages or other EV manufacturers' performance.
- Adding more context and comparison could make the article more informative and engaging for readers interested in the EV sector.

To improve the story, you might want to include more analysis and context, discuss trends in the broader EV market, and provide insights into how Rivian's situation fits into these trends.

Based on the provided article, the sentiment is mostly **negative** due to the following reasons:
