Let's not forget about human experience. It gives context to any visual perception, and can't be replicated by cars. We simply have access to a larger, more complex environment, and the environment fosters our intelligence. It's easy to overemphasise the brain to the detriment of environment, but in reality the environment is the main cause for the development of intelligence in the brain. The corollary is also true - a lower complexity environment will lead to lesser intelligence, no matter how powerful the brain is. Intelligence springs where agent needs meet with external limitations, those limitations guide its development.

By analogy, the environment is like the training set and the brain is like a deep neural net. A deep neural net with a poor training set is not going to be accurate. That's why DeepMind, OpenAI and others have focused so much on artificial environments (games) to train agents - they know that environments are the key to training advanced AI. A mere dataset is like a static environment where nothing new happens. Research is transitioning from datasets to simulated environments for the next step in AI. I'd even go as far as to track the evolution of AI by the evolution of environments and environment models.
