I think you can see the car steering all four wheels during the off-road trials.

This video is well worth watching. A very impressive machine, with what appears to be an exceptionally comfortable ride. It is lovely to see the person demonstrating the car so completely confident of his machine. 

At the end, the chain-smoking Colonel Witheringfoot-Smythe seems to be saying, "Jolly good show, old man! The Army will take 50 of these, money no object, provided you can supply them this week."
