Sometimes I wonder if Tesla also has a much better software stack than most other manufacturers. IIRC, Tesla has had interior cameras in their cars for years now and I haven't heard about major issues stemming from it.
It still falls back on the torque sensor (requiring hands on wheel) if it thinks you're not paying enough attention, or if it can't see your eyes for whatever reason.
And I guess Tesla must have enabled the camera for all new vehicles now, at least in Europe, given that it's required.
