As part of the concept of all-round visibility and as an element of safety and as a distinctive marketing feature, the glazed transparent area in motor vehicles has undergone a significant increase. Assisted electronic visibility, including the contribution of rear-view mirrors, sometimes seems to limit the trend towards enhancing visibility by means of glass. This paper shows that assisted electronics in place of direct vision reduces safety. In fact, assisted electronic visibility not only reduces perception times compared to direct vision, but also more glazing certainly contributes to improving driver-environment integration and increasing driving pleasure. Moreover, the creativity of designers and the skills of aerodynamic engineers can be more fully exploited.
