A California start-up is promising a flying car by 2025. Alef Aeronautics from the San Francisco Bay Area wants to start delivering its 300-thousand-dollar Model A flying car to customers by end of that year. Alef is already taking deposits from potential customers. It costs 150-dollars to get on the waiting list and 15-hundred dollars for a priority spot on the list. The company's CEO says building a flying car is no more complicated than a Toyota Corolla.
