Driving in India is notoriously chaotic and if self-driving cars are ever deployed there in our lifetime, they will come with a safety guarantee about equal to a car driven by a blind dog with a missing paw. It would be impossible to safely navigate the streets there with anything less situationaly aware than a fully developed adult human brain.

The article above makes it sound like weather is the big problem for self-driving cars and once that's solved- wooohoo, we're on our way! It's far from that. Self-driving car AI is still incapable of reasoning about its environment, neither does it have any "undersanding" of it in any way, shape or form. Consequently it only works in very limited environments, in very limited conditions - of traffic, visibility, road quality etc.
