Apwc must be operated in a reasonable and prudent manner. it is illegal to:
a) weave your pwc through congested waterway traffic.
b) swerve at the last possible moment in order to avoid collision (as in spraying another person or vessel, or playing "chicken").
c) jump the wake of another vessel unreasonably or unnecessarily close to that vessel or when visibility is obstructed.

A PWC must be operated in a reasonable and prudent manner. It is illegal to all the three mentioned points.

Explanation:

Weaving a PWC through congested waterway traffic may lead to fatal accidents due to narrow water path ways or some kind of obstruction. One must look for the clear waterway traffic to weave.

One should not operate in a manner that requires swerving at the last possible moment to avoid collision as doing so, again, may result in fatal accidents. It is always better for the operator to play safe while weaving a PWC as there is a very low chance of survival if, unfortunately, one meets with water accidents.

Again, it is never a good idea to jump the wake of another vessel unreasonably or unnecessarily close to that vessel or when visibility is obstructed as the visibility might be just an illusion which may result in unknowingly welcomed fatal accidents.  

glass wants to live in a world of super heroes and villains. he have lived all his life trying to be responsible for the creating the origin story of a super hero; he schemed and caused many incidents (many of them fatal) hoping that someday someone with superpowers would show up and save the day.

he knew himself very much. he saw himself as a villain of a real-life super hero story. he was aware of his strengths (more than smart enough for being manipulative and scheming) and weaknesses (having fragile bones and having to rely on his mind to succeed).
