Given that radar is functionally blind[1] to static objects when travelling at high speeds, I'd argue it's not just a good thing, it's a necessary thing. Tesla have demonstrated the superiority of their vision approach and validated it with 1,000 years of real-world driving, running it in shadow mode on customer vehicles.[2]

[1] Technically radar isn't blind to static objects, but since it cannot disambiguate them from tunnel entrances and highway overpasses, the data is useless. Therefore it's functionally blind.
