There’s around a million people dying from cars every year and we just shrug and normalize them. Human or not, we just have to have cars and “accidents” are just that.

The difference is accountability. If a human kills another human because of a car accident, they are liable, even criminally liable, given the right circumstances. If a driverless car kills another human because of a car accident, you're presented with a lose-lose scenario, depending on the legal implementation:

1. If the car manufacturer says that somebody must be behind the wheel, even though the car is doing all of the driving, the person is suddenly liable for the accident. They are expected to just sit there and watch for a potential accident, but the behavior of what an AI model will do is undefined. Is the model going to stop in front of that passenger as expected? How long do they wait to see before they take back control? It's not like cruise control, a feature that only controls part of the car, where they know exactly how it behaves and when to take back control. It's the equivalent of asking a person to watch a panel with a single red light for an hour, and push a button as fast as possible when it blinks for a half-second.
2. If the model is truly driverless (like these taxis), then NOBODY is liable for the accident. The company behind it might get sued, or might end up in a class-action lawsuit, but there is no criminal liability, and none of these lawsuits will result in enough financial impact to facilitate change. The companies have no incentive to fix their software, and will continue to parrot this shitty line about how it's somehow better than humans at driving, despite these easily hackable scenarios and zero accountability.

Humans have an incentive to not kill people, since nobody wants to have that on their conscience, and nobody wants to go to prison over it.

Corporations don't. In fact, they have an incentive to kill people over profits, if the choice presents itself!
