Sinking Wheel Fix!

Have you ever made a top of the line landmaster tank, with the brand new, sexy, phoenix wheels… that spin smoothly unlike the regular wheels… just to watch the wheels sink into the ground and your landmaster hump the dirt!?
I’M TIRED OF THAT. I have to make my cars go 5mph or else the wheels just get “flat tires”. And NO I don’t put a bunch of stupid options on the wheels like 500,000,000 torque >=/

Someone please save my Batmobiles, and T-rex’s, and Landmasters, and Rocket-penis-mobiles! Make the wheels stop sinking! [that includes sinking into other props]

That would require editing the Havok source code, right?
