Collision problem within Junior Programmer Path unit 1

Unity Engine
,
1

I recently started the Junior programmer path and I am now stuck at Unit 1.2, This is my problem:
I sat everithing up as explained by the lessons.
I have a car on the road and a box.

Position of the car is been given by the following code snippet on the update fucntion: transform.Translate(Vector3.foreward* Time.deltaTime*20); as shown in the tutorial.

Both veicle and obstacle have a rigid body component.

The car keeps “Bad” colliding with the box. A collision i detected but the box gets gliched trought the car and not really much happens. For some slower speeds The car jumps over the box, it almost looks like the box fights to stay at is cordinates. I also tried givin 1000 mass to the car and 1 to the box with no results: Box still glitches or bounches the car away. This is really frustrating since I can not manage to go on, Does anybody have any Ideas to troubleshoot or is willing to try this out on his machine and see if Similar results are archieved?

Check if the tutorial tells you to mark things in the Physics collision matrix, which might be how they get certain parts to ignore collisions. You can see this matrix in Project Settings ->Physics at the bottom, a big grid of checkmarks.

Other than that you sorta gotta just back up and make sure all the parts you did so far are indeed done properly.
