Here are some links to help you understand the meaning of your dream:
car

crash
Given your previous dream, one interpretation might be that you (the car) want the young man to "go fast" with you (perhaps in a relationship sense?). Take note that you have him in control of the car (you), but you goading him on. The crash reflects your concern that you and/or he might lose control and "crash."
It doesn't mean that you want him, you or your relationship to crash... only that you have concerns that going too fast might make it happen. See how wise you are?
The answer...
Go slowly, wear your seat belts, and enjoy the ride.
