Criminal Sentence 204: Like, Totally

From a book I finished last week:

"Like getting on a boat, you wait for permission [to come into a room]."

This is a classic faulty comparison because the sentence compares "getting on a boat" with "you." Not really possible. I know we speak like this all the time, but when we write, it's better to be more precise:

"As when you're getting on a boat, you wait for permission."

This sentence compares "you" and "you." Like, totally correct!
