The DeLorean car plays a significant role in all three films since it is the time travel machine. At the end of the first film, we’re shown a brief scene (that is repeated at the beginning of the second film) that reveals that the vehicle has been modified so that it flies. Even its modified form it is largely like a car from the period. The driver or pilot manually drives the vehicle with no software assistance or heads-up-display.
I might have strong opinions about the controls of a car being poorly mapped to manage flight, but since this is a hacked-together prototype from materials at hand, it’s less a design problem than a matter of circumstance.
