can u do anything about saws /drills not causing damage unless the vehicle is stationary, with wheels having basically no traction i find mining on slopes hard as u cannot stop the vehicle from sliding witch means the drills do 0 damage to rocks and saw do 0 damage to wood,

Unfortunetly not, Thats all part of the games physics which i can't reliably alter, The work around for that issue is to put drills and saws on pistons and use their compression to keep it working
