Shock absorbers like bumpers on cars
Building drop pods and rovers is now a lot of fun in Space Engineers, but whenever anything big enough or going faster than 5 m/s scratches the voxels, you are lucky not to lose a few large thrusters in that incident.
I'm also impressed how well wheels (if you manage to land on them first) can survive 50 m/s impact, maybe this is some sub-grid physics that is protecting the rest of the ship here.
I now think, what if a 1x1 bumper block made of rubber was touching a voxel and only slowly passed on the force of an impact to the rest of the ship to save it? I could use it like on bumper cars to save me from a few accidents. It could also help guiding through smaller tunnel networks, like lubricant oils.
