Yes, but even then you should be referring to a single instance of driving to and from work. If you’re speaking generally, you would still use “costs” because that implies an ongoing situation.

“On Thursday, it cost $70 to drive to work” would be appropriate.

I think that the commenter is referring to the grammar. It should read “it costs,” not “it cost.” It makes it seem like they are referring to a very specific previous drive, but that context isn’t provided here

I think they meant literally, “it cost” as in past tense. If you’re referring to a specific, previous event, then it makes grammatical sense. But it sounds like he’s comparing the cars generally, so it sounds more appropriate to say “it costs”
