I'll take this slow for ya. I don't know the exact stopping distance for the X, but let's say it's 140 or so feet from 60 mph. If you're doing 60 mph and can't see well over 140 feet in front of you, you are overdriving conditions. It's very simple really. It's common sense. If you're going around a corner at a speed that requires you to swerve around an obstacle because you don't have time to stop, you are overdriving conditions. It's like fog--if you can't see 150 feet in front of you, you shouldn't be doing 60 mph. I don't know how much simpler I can make it for you. Those 200 people who just piled up in the fog surprised me at first. But I guess, as you are an example, that thought process is normal.
