Newton's first law states that an object at rest will stay at rest and an object in motion will stay in motion. So when the car is not moving, the dice will hang directly downwards, being pulled by down by gravity and up by the force normal created of the mirror, equally. But if you start to move forward, then the dice must react in some way, because it is being affected by motion. So the dice will now gravitate towards the back of the vehicle.

You don't notice it but your body is also pulled toward the back of the vehicle. The difference is that you can see the dice. In fact, when you first start to accelerate in your car, you can feel the pull into your seat, but soon you get used to it, and that is what's called relativity.

So the you and the dice are being pulled toward the back of the vehicle, and you can calculate how powerful that force is using F=ma
