The proposed price signal is "the more expensive, the better". So forbidding car ownership, in other words. A deeply destructive point of view.
No need to be dramatic here. First, it's not "forbidden," just expensive. And the cost reflects the level of risk. Insurance companies aren't charities, and the marketplace is competitive, at least.
The US is still far cheaper to drive in, by comparison.
To elaborate, maybe: I would fully support a robo-taxi scheme to ferry people to and from their job, shopping, or whatever. Where I live, shared e-vehicles are as good as it gets right now, but that's definitely a promising step already.
