So, Elon Musk is the boss of a company called Tesla that makes electric cars. Electric cars are special because they don't need gasoline to run, but instead use power from batteries. Toyota is another car company and their boss, Akio Toyoda, said he thinks only 30% of all cars in the world will be electric like Tesla's. He thinks other types of cars that use different kinds of fuel or don't need any fuel at all will still be popular. Elon Musk doesn't agree with this idea and believes most cars in the future will be electric, just like how cars replaced horses a long time ago. Read from source...

- The article presents Musk's reaction as a simple "sigh", which implies that he is disappointed or annoyed by Toyota's views. However, this does not capture the complexity and nuance of his response, nor does it account for the possibility that he might have different emotions towards different aspects of Toyota's statements.
- The article focuses on the contrast between Tesla's product portfolio (only battery electric vehicles) and Toyota's (a full lineup of multi-pathway products), but does not explore the reasons behind their strategic choices, nor the potential advantages and disadvantages of each approach. For example, Toyota might have a more diversified strategy because they want to cater to different customer preferences, markets, or regulatory environments, while Tesla might pursue a singular vision of electric mobility for its own reasons.
- The article quotes Musk's statements from the past without providing any context or evidence to support his claims. For example, he said that he sees electric cars replacing combustion cars as cars replaced horses at the start of the 1900s, but did not specify what timeframe or conditions he has in mind for this comparison. He also said that hydrogen is a "dumb way to store chemical energy", but did not explain why or how his battery technology is superior to other alternatives.
- The article does not mention any sources of information or data to support the claims made by either Musk or Toyoda, nor does it provide any analysis or evaluation of their credibility or reliability. For example, it would be useful to know what research or projections they are basing their forecasts on, how they define and measure CO2 emissions, and what criteria they use to compare different vehicle technologies.

Bearish on Tesla and Elon Musk. Toyota Chairman Akio Toyoda sees battery electric vehicles securing no more than 30% of the global automotive market share, leaving the majority to other fuel technologies including hybrids, hydrogen fuel cell vehicles, and conventional combustion engine vehicles. This is contrary to Tesla’s product portfolio which involves only battery electric vehicles.

Based on the article, it seems that Tesla CEO Elon Musk is quite confident in the future of electric vehicles (EVs) and sees them as a major part of the global automotive market. He also criticizes other fuel technologies like hybrids, hydrogen fuel cell vehicles, and conventional combustion engine vehicles. However, Toyota's chairman has a different opinion and believes that battery electric vehicles will only capture a small portion of the market share, leaving room for other alternatives.

Investment recommendations:
- Consider investing in companies that are leaders or innovators in EV technology and production, such as Tesla Inc (TSLA) or other major automakers that have announced plans to expand their electric vehicle offerings. These companies may benefit from the growing demand for EVs and the shift towards more sustainable transportation solutions.
- Be cautious of investing in companies that are heavily reliant on traditional combustion engine vehicles, hybrids, or hydrogen fuel cell vehicles, as these technologies may become less popular or obsolete over time due to environmental concerns and advancements in battery technology. Examples of such companies include Toyota Motor Corp (TM) or other automakers that are not yet fully committed to electric vehicle development.
- Keep an eye on the regulatory environment and government policies regarding EVs, as these may have a significant impact on the adoption rate and market share of battery electric vehicles. For example, if governments implement stricter emissions standards or incentives for EV purchases, this could boost the demand for electric cars and benefit companies that are well-positioned to meet this demand.

Risks:
- The adoption rate of electric vehicles may be slower than expected due to factors such as high costs, limited range, lack of charging infrastructure, or consumer preference for traditional vehicles. This could result in lower sales and revenues for EV manufacturers, and a more gradual shift towards sustainable transportation solutions.
- Technological advancements in battery technology may lead to faster charging times, longer range, or lower costs, which could make electric vehicles more appealing to consumers and reduce the need for alternative fuel technologies. However, this could also increase competition and innovation in the EV market, making it harder for some companies to maintain their market share or profit margins.
- Government policies and regulations regarding EVs may change over time, either becoming more supportive or less favorable for electric vehicle adoption. This could have a significant impact on the demand and supply of battery electric vehicles, as well as the competitive landscape of the automotive industry.
