obswerveation
When you spot a problem in your way and you make a quick move to avoid it, or you see someone else's quick move and think, 'I hope I don't have to do that.'
I saw a dog in my lane and almost hit it. I turned so hard I almost fell out of my seat.
I saw some skid-marks and thought, 'That guy must've been in a hurry.'
I saw a car swerve and almost hit a truck. I thought, 'That was a mess.'
