The picture of a driver hopping out of the car "better exemplifies" the differences between piloted and autonomous driving, di Grassi said. He also argued that racing needs a "human component." While it's not certain that people would lose the plot with completely driver-free cars, it's true that there isn't as much of a stake in the race when it's simply a competition between AIs.

Di Grassi noted that the first season, which will support Formula E races, will likely include fewer than 10 cars. Roborace will provide the hardware and logistics, with teams providing the software to both foster development and lower costs. The schedule for this inaugural run should be available by the end of 2018.

There's an upshot to this method: when there's a finished product, it could be particularly impressive. Di Grassi sees the 2021 vehicle packing over 1,341BHP (about 1,359HP) with four electric motors providing power at each wheel. Whether or not there's a driver, it could represent a good example of EV racing in action -- and it'll be much more substantial than a hill climb.
