If you want us to actually care about their relationship, then show it . Begin this story with a scene between them, showing how they handle conflict resolution in a happy way, showing her as a funny, interesting person, giving her quirks that are endearing and showing a relationship founded on something other than lust or pride in a trophy wife. Let us find out about the pregnancy, not because of thoughts, but because they talk about it, because her belly is beginning to get in the way of her work, etc. Unfold the relationship in a scene that is about something. Now , the story finally comes to life when you have the traffic confrontation.
Guy driving to work, that's perfectly normal.
You want an action start, this one works. Plenty of time to get the other stuff while he's sitting at the side of the road, sans windshield, waiting for the cops. Definitely a distant voice, narrator firmly in charge. Start with a scene at home, funny, interesting, idyllic, and then interrupt it with the traffic incident. The story will be interesting enough if you make the relationship interesting enough.
