It's creepy because this comment was written before famous tesla roadster launch

나는 here means 'flying,' the modifier or adjectival form of 'to fly = 날다'. The ㄹ disappears when the verb changes to an adjective, as with 울다 (to cry) and 우는 (crying). But I can see the confusion-- 나는 also the informal word for 'I'!

That's the part that means "the flying (x)."

It means flying as well as I

나는 means flying

Same here

It means flying in this sentence

Significaria 'ser barato'

It would mean 'to be cheap' price-wise
