I'm going to make an old person driving to make a sudden stop
I cannot understand your reasoning for doing this. Why would you do that to an old person?
I love causing old people accidents.
It is really bad to try and cause an accident intentionally. You could hurt or kill people by doing that.
I was only making an example.
An example of a situation that is dangerous to someone is bad. You should not take actions that will injure people.
