    Helicopters aren’t failures, people still use them to get from the city to an airport and back. However, they are very expensive.

    The vehicles in this article have the same use case, but they are intended to be cheaper.

      These drone cars won’t be cheap either.

      Because it costs a lot more energy to keep something in the air and move it forward, than it is to move it forward on the road.
