I'd potentially need several seconds to figure out what is going on. I would hazard a guess that an approach that might be more fruitful be to have a meter that dynamically adjusts the "riskiness" of the situation between a yellow, orange, and red zone, so that the driver (a) has to pay attention constantly, (b) gets information constantly, and hence (c) has a better chance to react earlier. I know if I see a "danger meter" getting into the orange zone, I'm not going to wait until it goes into the red before I start paying attention.
