How do I stop a Ragdoll passing through fast moving colliders?

G'day all,
I am having a little issue with my game (I use the term loosely at the moment)
I have a Ragdoll character which I move, snapping to a grid, locked via the Root Joint to the Y axis... It is still pretty rough but I am getting there. The idea is to (eventually) move the little guy to avoid oncoming obstacles moving at ever increasing speeds.
Pretty simple thus far but my issue at the moment is that if the approaching obstacle/GameObject is moving with any speed my Ragdoll will pass strait through it and not collect/hit/impact it...
As I write this I am realizing that I haven't yet tried to disable the Y-axis lock on "impact" but I will still post this just in case someone has a better idea.

I will try to attach a short video(Added as .zip can't do mp4) (I am manually controlling the approaching cube...) of what I am talking about and the 2 scripts that are on the player. Also I have checked that all colliders are not set to Triggers, Rigidbodies are not Kinematic and "Use Gravity" is not selected.

Any help would be greatly appreciated.
PS: kinda new to C# so please forgive me if my code looks odd.

raycast last position to new position, if it hits anything, set coords to last position and set velocity.normalized to 0
