I try to make the concept realistic enough for the near future.
The car has step engines, so she won't be as fast as a sport car, but the extremely high precision is perfect for automatic controlling. The omni mechanism of the front wheels allow the car turn very easily, especially in a overpopulated city.
And of course she's an electric car with wireless charging system.
