If only all automakers treated visibility as seriously as Volvo. This S80, for example, is one of the easiest sedans to maneuver in traffic, thanks to narrow pillars, headrests that set down into the rear seats, and the wonder of Volvo's Blindspot Information System (BLIS). Dare we say it? The little lights located on the A-Pillar beside the rearview mirrors, are, uh, a BLISsful bit of technology. The lights blink when a car enters into the blindspot zone on either side, silently and subtly notifying the driver. Add to this the turn signal indicator lights on the rearview mirrors themselves, and it's hard to imagine a lane change accident. The BLIS system helps even more so, because the rearview mirrors themselves are a bit small.
