> What if it being optional increases death statistics massively?
What else would you like to make mandatory to satisfy your death reduction statistics, I wonder? Vaccines?
Let's just go all the way: you're talking about eliminating human agency, autonomy and free will. You want to replace it with decisions made by committee with optimized outcomes and make them mandatory with force of law.
> Should we really be ideologically driven instead of relying on data and measurable effects?
Yes. Do you not have principles, values you won't compromise on?
The argument isn't that a human is better at avoiding accidents than an automated system, the argument is that, as an average human, I'm good enough and the marginal difference isn't worth the complexity and risk that the system introduces.
Absolutely not. There are other people on the road. Families. You don’t get to kill other people in a preventable accident because you believe you’re an above-average human who can outperform a computer.
