The question isn't whether it can be done eventually, but whether it would get safer faster with extra sensors.

Back in the day, Elon's specific objection to lidar was that it was too hard to code the sensor fusion part. With end-to-end there's no coding to deal with.

And it's not like they've replicated the visual cortex. It's the same neural net technology everybody else is using. It can deal with any sort of sensors just fine.
