You have already been told. The Prius is not complex at all. There is
less components in it - not even an in-line gearbox. It is just that
your mind can't figure it out.

Just 'cos it's sun and planet doesn't make it not a gearbox.

No mechanical clutch *is* a worthwhile feature, especially to owners of
dual-mass flywheels. But I'm not convinced that two electric motors and
a darnn great battery pack count as simpler than a clutch.
