Perhaps it is my height (1.91 m) and seat adjustment, but concerns about rear visibility seem to be intentional design by Toyota engineers. Daylight rear visibility is adequate, side mirror viewsheds can sometimes be marginal. Night time visibility is enhanced by the rear air deflector and horizontal window below the deflector. The deflector helps reduce headlight glare from following vehicles. Visibility is "clear" except for the glare of direct headlights. A nice touch.
