It really is a bad idea. You have no idea. A car and a part time job are just the most basic aspects of teen life. And by most basic, I mean everyone has that. Having a baby is a huge responsibility. Get a cat. Get a dog. Get a goldfish.
Go out and have fun. Go to the mall (without pushing a stroller). Go to the movies. Go to dances. Hang out with your friends. And all the while you are doing those things, remember that when you have a baby at 16 you don't get to do stuff like that.
You have plenty of years to be a 'grown up'. And only 7 years of being a teenager. It goes fast, enjoy it while you don't have any responsibility. That will all show up soon enough.
A baby is not the answer to any question you seek.
