What if Newton's 1st law of motion is modified?

Newton's first law of motion states

An object remains with the same velocity, or position of rest unless an external force is exerted.

What if we created a hypothetical universe where

An object in motion tends to accelerate at $0.001\ m/s^2$ in the same direction as its original motion without external force. Objects at rest stay at rest.

In other words, space itself exerts a force on every moving object, without affecting the (space) itself.

All other fundamental principles such as gravity being a force, force being the rate of change in momentum, etc. are the same. All laws that do not rely on this law are the same.

Can the universe exist? Can it exist in a form similar to ours? Suppose some intelligent life forms of that universe were given our technology, which are the most important ones that will still work (or not work)?

And finally, could a Big Bang have created this universe, and can it sustain itself and grow?

Extra Q

Does it matter if I give the acceleration a different value? Or a negative one?
