One look at the SX4's greenhouse, and one might logically conclude that visibility isn't a major issue. Indeed, we had very little trouble in this regard thanks to the tall side glass, the wraparound rear quarter windows, and the small front quarter glass in the doors that offsets somewhat wide A-pillars. The B-pillars are narrow enough to allow for easy over-the-shoulder checks when merging. Other pluses included retractable rear headrests that allow the most to be made of the expansive rear window, and spacious exterior mirrors that were quite effective in eliminating any nasty blind spots.
