I have some questions about the lv22 cleric utility power Cloud Chariot.

Can the chariot hover or must it stay in motion when aloft? If so, at what speed?

What rules and modifiers come into play if characters used ranged attacks from the chariot above the battlefield?

How much weight can the chariot hold?

Does the cleric who conjured the chariot have to be the one to direct it? If not, can the cleric allow others to direct the chariot while the cleric stays behind? If so, is there any limit to how far away from the cleric the chariot can go? Can the chariot be directed to go somewhere while empty?
