Well...it sounds like you're still asking if you can use them on vehicles with that example. All of your abilities get transferred onto a vehicle while riding said vehicle, though sometimes that might not be the best choice, such as Shadow Shot's shadow clones. Ultimately, it's up to your judgement on whether using a certain ability on a vehicle is the best choice since not all abilities are going to be the ideal choice while riding.

Hope that helps.

Edit: Oh now I see. No, your abilities do not get transferred to the vehicle itself.
