• Tesla demonstrated a flying Roadster prototype using compressed-air thrusters.
• The vehicle's flight capability is not approved for public-road use.
• Production is targeted for 2028, but significant engineering and regulatory hurdles remain.
• The company faces challenges in industrializing aerospace-grade pressure vessels and valves.

Tesla's flying car ambitions may indicate a shift towards more experimental and high-risk projects, which could impact the company's reputation and investor confidence. The significant engineering and regulatory challenges ahead suggest that the 2028 production target may be overly ambitious, and the company may need to revisit its timeline and expectations.
