Can I cut off a person?
Why would you cut off a person?
I am going to cut them off because they are going too slow for me.
Doing something like that is very risky and bad. It's bad to drive aggressively. You could hurt yourself or others by driving that way just because they are going too slow for you.
It's not like they have to slow down for me, I am just going around them.
It doesn't matter. You could cause an accident by driving so aggressively and die.
