Nah, 2 lanes are pretty manageable. Even for a pedestrian. You still only have traffic coming from one direction which makes it easy to see when you can cross.
From a car perspective, it's just a matter of getting in the right lane for the exit you want.
A disaster for cars, at a slower speed and similar direction than the comparable intersection (and no racing to/from from a light psychology).
So a disaster with significantly better outcomes than a red light runner (with a high speed side swipe or head collision)
