Update 2023-09-25: Added magnet versions
These blocks (ab)use the bumper mechanic to just apply force in the indicated direction. Try driving on them forwards, sideways, backwards, etc.
Made using mesh modeler and E++
They work by canceling out the Y (up/down) component of bumpers. Then you just have pure force application left. Using E++ you can create your own variants with different surfaces. Set the y component of Shape/Surface > GameplayMainDir to -5 for bumpers and -3.75 for bumper2s. Then set the x/z component to whatever you want depending on desired force. Usually this is on the scale of 0.2 to 0.01.
