A self-driving car, as proposed by Waymo and many others, in no way relies just on GPS. These beasts have fusion of many sensors with built in redundancy.

Technology improves and evolves. If it didn't you wouldn't be so reliant on Google Maps. We convince people of progress by a safe track record. Google maps may fail occasionally but more often than not it gets you to your destination at the estimated time.

Yes self-driving cars can't be "more often than not" safe. But starting with smaller areas and showing the difference it makes on people's lives and the environment can be a good start.
