Also, what happens if they are going the other way and crash into each other, would the impact speed would be close to 2x the speed of light?
Now you get to the whole point about relativity. This question has a different answer for each observer. Someone in a car would see the other car approaching at 0.994c (see my previous reply).
However someone on Earth looking at each car will see them each moving at 0.9c
