"Skycar" is described as a light aerial multi purpose vehicle set to make its world debut in the United States; which company developed this innovative Skycar model?

Introduction / Context:
This question relates to futuristic transport technology and business awareness. The "Skycar" is a concept of a light aerial multi purpose vehicle that blends features of a car and a small aircraft. Knowing which company developed this model helps candidates understand how smaller innovative firms, not just traditional automakers, are involved in experimental personal flight vehicles. Such questions often appear in general knowledge sections that cover science, technology, business and innovation together.

Given Data / Assumptions:
- The product mentioned is "Skycar", described as a light aerial multi purpose vehicle.
- It is said to be ready for a world debut in the United States.
- The options are Ford, Audi, Rolls Royce and Moller International.
- We assume the question refers to a specific prototype and company that has worked on personal vertical take off and landing vehicles.

Concept / Approach:
Moller International is a company founded by Dr. Paul Moller that has focused on creating personal vertical take off and landing vehicles, including the Moller Skycar series. The Skycar has been presented as a concept vehicle that could provide personal air transportation for short distances, subject to regulatory approvals and technological refinement. Ford, Audi and Rolls Royce are established automobile or aerospace names, but the specific light aerial multi purpose "Skycar" with high media attention has been linked to Moller International rather than to these larger companies.

Step-by-Step Solution:
Step 1: Identify that "Skycar" refers to a hybrid vehicle with car like and aircraft like features. Step 2: Recall that Moller International has long worked on the Moller Skycar project, which attracted global curiosity as a personal flying vehicle concept. Step 3: Compare the options: Ford, Audi and Rolls Royce are major automotive or engine brands, but they are not the primary names associated with the Skycar prototype described. Step 4: Conclude that Moller International is the correct answer.

Verification / Alternative check:
One can verify this by remembering news and documentary segments that have featured the Moller Skycar, often referring to the company by name and showing its founder explaining the technology. Ford and Audi focus on road vehicles and electric or autonomous driving platforms, while Rolls Royce is known primarily for luxury cars and aircraft engines, not for a personal Skycar demonstrator. This distinction makes Moller International the only option that fits the description of a small firm devoted to flying car concepts.

Why Other Options Are Wrong:
Ford: A major automobile manufacturer, but not the developer of the specific Skycar concept vehicle mentioned here.
Audi: Known for high end cars and design innovation, yet not connected with the prototypical light aerial Skycar developed by Moller International.
Rolls Royce: Famous for luxury cars and aircraft engines, but not the creator of the personal Skycar vehicle described in the question.

Common Pitfalls:
Candidates may be tempted to pick a big brand like Ford or Rolls Royce because the idea of a Skycar sounds expensive and technically advanced, which seems suited to large companies. However, many radical innovations begin in small specialised firms or start ups. Another pitfall is to assume that any new aircraft related technology must be linked to Rolls Royce due to its aerospace reputation. To avoid such mistakes, pay attention to company names that repeatedly appear in innovation stories, such as Moller International in the context of flying cars.

Final Answer:
The light aerial multi purpose vehicle called "Skycar" was developed by Moller International.
