So, to the designers and engineers in the house we ask: how important is reducing the amount of glass in a vehicle improve safety test performance? To what extent does this issue drive design?

Can you identify a point at which introducing more glass to a design makes a car look dorky but creating a tighter greenhouse hurts usability (and possibly even active safety)?
