I thought it was anything below 4, but who knows. When I have unsafe drivers I aggressively rate them 1 or 2s depending on what it was. I know that it's "mean"

I thought it was anything below 4, but who knows. When I have unsafe drivers I aggressively rate them 1 or 2s depending on what it was. I know that it's "mean" to the driver, but I'm being kind to future passengers, pedestrians, and everyone who shares the road.
