I've found that what is more important than making a good/bad decision, is sticking with the decision I make, with the possibility of mitigation measures, if it turns out to have been a bad decision. Sometimes, I can pre-plan mitigation measures, or I research them quickly, when it becomes clear that I made a mistake.

Jamming on the parking brake, when going 90, down the highway, is a bad idea.

I sometimes miss a turn, or don't plan well enough to be in the correct lane, when I arrive at the intersection.

What I do, is go "D'oh!", continue to the next intersection, then either make a U-turn (if legal), or turn onto a side street, with the intention of recovering my intended direction.

What I often see people in the same situation do, is jam on the accelerator, swerve across six lanes of traffic, and screech into their turn.

That may get them where they are going, but it also has a very real chance of earning them a ticket or a stay in hospital.

My way takes a bit longer, but no ticket, no accident.
