That is an incredible shot, I have never seen it so close, certainly dev commands at use. But still quite remarkable, thanks for posting. And yes it's a 'chariot', a wagon of sorts. But, those wheels belong to daddy, thor is just out on a joy-ride.

Odin's Volk
The wagon is often found linked to the god Freyr, His image was carried around in a wagon in Sweden until late in the Heathen Era. The wagon like the ship, is associated with the mysteries of fertility, life, death, and rebirth. and is seen as a vehicle to the other worlds.
