While thrilling, there is a chance that you would have an accident if you elected to drive on the wrong side of a divided highway in woodward, an outcome that could be described as:?

I believe the answer is: High in consequence and high in probability.

An outcome is considered as high in consequence is it posses high level of danger for the actor (such as death, financial bankruptcy, fatal injuries), and an outcome is considered as high in probability if the chance of its occurring is significantly high.
