Why is the result of glimpse() a tibble for some but not all data?

So I'm running some code on a dataset that is 9992 rows and 10 columns. Specifically, I'm checking if the dataset's glimpse is a tibble, i.e., data %>% glimpse() %>% is_tibble(). It is outputting TRUE. But on other datasets, like the cars dataset, I'm getting FALSE. Why might this be the case?

I ran data %>% glimpse() %>% is_tibble() and cars %>% glimpse() %>% is_tibble()

tibble dplyr r

glimpse just prints the data in a transposed way and it does nothing on the data. The is_tibble will return TRUE only if the underlying data is tibble. Here, cars is not

> class(cars)
[1] "data.frame"

If we convert to tibble, it will show TRUE for is_tibble

> cars %>% 
  as_tibble %>% 
  glimpse() %>% 
  is_tibble()
