Automotive charging systems that actually sense current are
EXCEDEINGLY RARE.

I've never seen one.

You just have. His Renault clearly is reducing the voltage once
it has decided that the battery is fully charged and that can
only be by sensing the current that the battery is taking.

It looks at the *voltage*. It operates on the *voltage* and it alters the
voltage according to the needs of the battery and the rest of the
electrical system.

The voltage doesnt tell you when a lead acid battery is fully charged.
