It's impossible to say what was the exact waking life background that generated your dream, but the symbolism in your dream is common. Because dreams are symbolic expressions of your feelings about your waking life and cars are symbols of the self, your dream suggests that you feel out-of-control in your waking.... but not as in you are going to crash. Instead, it seems to say that you feel as if your life is on autopilot. In the dream you are trying to take control of the steering wheel... as if your life (perhaps involving job, relationships, family, health issues) is in control of your life (as you chase it)... not you consciously.
Here's a link to the definition of a car on this website:

As for what is the area of your life "is driving you," there are a number of clues, including the people in the dream, who may be symbolic of people or situations in your waking life. The religious symbolism is another big clue... which again could be literal or symbolic.
The good news in the dream is that at the end of it, you do grab the steering wheel. This is often indicative of the fact that you know you can do it if you try... you just have to get out there and do it.
Hope that helps! Good luck!
