Once computers and AIs can approach even a small fraction of the our capacity then sure, only cameras is fine, it's a shame that our suite of camera data processing equipment is so far beyond our understanding that we don't even have models of how it might work at its core.

Even at that point, why would you possibly use only cameras though, when you can get far better data by using multiple complementary systems? Humans still crash plenty often, in large part because of how limited our "camera" system can be.
