I think the robotaxi might be the only actual viable approach to developing fsd.
You control the hardware and software, you drive in real world conditions, you can deploy regionally and control the hours and conditions you operate in letting you gradually increase when you operate as you judge it safe.
And if the robotaxi makes a mistake, well it's still in testing phase/beta.
If Tesla comes out with FSD then it has to be damned near "perfect" in all conditions, which just is never going to happen out the gate?
You can even design some type of system where the taxis can only physically go on a routed road, and then you won't have to worry about real world conditions. And then you can just integrate some sensors into the routed roads to detect the vehicles' location and then you can guarantee they'll never crash.
Oh! Oh! And then for efficiency maybe you can chain a ton of robotaxis together, so you only need one drivetrain... wait a second...
