When it is harmless to listen to your gut--probably should
When it has a cost, that's when you need to think. I realized today, returning to Bowie from WV, whenever I'm on the DC beltway, sometimes I look ahead and think--slowdown coming, so I tap the brake, and am always right. Sometimes it's obvious why I thought that (brake lights), but not always. Sometimes it's things like lots of people following lots of people closely so one brake tap could cause a chain reaction--and in beltway-quantum-theory, what's not prohibited is practically mandatory! (and sometimes what is prohibited...) Or something I never consciously noticed. I just call it "experience". Same way you know a guy is about to cut you off because you see his head turn your way as his rear bumper aligns with your front bumper, or see him subtly move your way, or something else entirely.
