Quickly is used when something happens in a short time interval. The car went from place A to place B very quickly. I don't see any example of a car going quickly in ngrams https://books.google.com/ngrams/graph?content=car+is+going+quickly%2C+car+is+going+fast
Okay, since it won't accept "the car goes very fast", how would I say that in Czech?
I had the same question. Which Czech verb is used in "The car goes very fast"?
