I'm assuming you're referring to the ability of a card such as Prophetic Prism? Thanks to all of you who gave answers. I appreciate the specifications!! Happy playing!
Can I attack with a vehicle without it being crewed?
This is no big deal, but in the future, please create a new thread for a new question instead of posting in an existing one, especially if that existing thread is old (more than a month in this case), even if the question is about the same category of cards. This helps keep threads short and focused and makes them a better searchable resource. With your question answered below, I am locking this thread to avoid it becoming a repository for future questions about vehicles. Thank you for your attention.

1: Can a Vehicle attack on its own without being crewed either by another creature or the effect of a spell?
2: If I use Emrakul, the Promised End as a Commander, do I have to use just colorless mana for my mana base or can I use any color mana?
3: If I use Emrakul as my Commander, can I use cards like Deceiver of Form and Kozilek, the Great Distortion?
