So I saw this xkcd, and when I tried reading it, I always felt like the ending was a bit... unbalanced.
You're in a box on wheels hurtling along several times faster than evolution could possibly have prepared you to go. (Next 5 miles.)
I can't figure out what's wrong with it, though... it's as if some word (e.g. "at"?) was supposed to follow the word "go".
So I was wondering, is the sentence grammatically correct, or is it indeed missing something?
If so, what?
