Recentish Range Rovers are easily the worst. But most SUVs are generally pretty bad, with speed bumps, slight hills, or - yes - even a simple right-hand bend giving you an eyeful of piercing cold light. With the modern HID-/LED-/etc.-type bulbs, there's no falloff at the edge of the beam, so the moment your eyes are even slightly inside the light cone, they get zapped.
I drive a BMW 3 series, which I don't believe is an especially low-riding car, but I still notice this quite a lot! I'm 6'2" and have the seat basically bolt upright, so my eyes are pretty far off the ground.
The biggest problem is how well are the other vehicle's headlights aimed. When i'm on the highway at night, i find that the Mercedes and Range Rovers with their HIDs are never an annoyance, because the lights shine at the ground rather than into my windows. GMC/Chevy SUVs and Pickups seem to be the worst offenders - they've got the xenon lights, but they're just a drop in replacement for the standard headlamps, so they shine straight out in front.
