The Strider behaves very strangely in water. When steering in one direction it effectively drifts to the opposite side, i.e. steer left and the Strider strafes almost 90 degrees right. The point around which the vehicle turns is actually in far front of the vehicle. It doesn't look like a vehicle actually being in water.

Expected:
Let's assume the Strider has propeller pods in the rear (since the RL counterpart is not amphibious), then it should almost turn on the spot when in the water. The turn radius should be reduced, the behavior would seem more like over steer.
