YouTube star CGP Grey does an excellent job of explaining why humans inherently suck at driving, and why self-driving cars can do it so much better. It’s probably all arguments you’ve heard before, but the concise explanations (and cute graphics) are enough to cure the most Miata-loving sceptics.
The video focuses on the traffic-calming benefits of self-driving cars that communicate with each other. As Grey explains, one of the inherent problems with human drivers is over-braking, causing traffic backlogs for no good reason. Self-driving cars can smooth out the system, much like managed highway, but on a far greater scale.
The true benefits of self-driving cars as depicted in this video are a ways off. For intersections to be completely re-done, you’ll need human cars to be banned, which will take far longer than just getting fleets of self-driving cars on the road. But in the meantime, non-connected self-driving cars can still improve safety and free up the time humans used to spend driving, no small thing on its own.
