(CNN) – That flying car you’ve been dreaming about since you were a child could be reality in a few years.
At least four companies are planning to produce, sell, and deliver flying cars to customers in the next few years.
One of them, Aero-Mobil, plans to start accepting deposits to buy the cars in 2017.
But some experts warn that timeline could be wishful thinking.
The cars must pass numerous tests to prove they are fit to ride and fly. And getting the proper permits and certifications can take a while.
