Riddle me this ?

[Unknown]

Late one evening, a man and his wife were driving their car at speed down a country road. The car spun of the road and hit a tree.

The man decided to seek help at a garage a few miles away.
He made sure nobody was in the car, rolled all the windows up, and locked all of the doors.
When he returned, his wife was dead, and there someone in the car he had never seen before.
No physical damage was done to the car, it was still locked?
How did the woman die?
Where did the stranger come from?

 

[Hello!]

the stranger was a baby and the woman died giving birth.
