florida driving school

My little sister is getting her driver's license in Florida. She is going to be on the road with all those little old ladies down there. I am scared and excited for her all at once.  She already got her Florida learners permit. I took her on her 15th birthday for that. I have to say I am a pretty cool big brother. We went down to the DMV while I was there for break, now THAT is a cool brother. Who wants to spend their school time off at the DMV? I can't think of too many more annoying places to be, except perhaps behind those little old ladies driving in Florida. 
So now she is turning 16, and I cannot be there to take her for her test.  I'm sure she doesn't care, I just thought it would be a cool thing to be there for her. I quizzed her over the phone with questions out of the Florida Drivers Handbook, she knows them all.
But can she parallel park? That was the tough one, right? Shoot, I did it for the test, but I still have a hard time, it's not the kind of thing that comes up very often. She is nervous and says she doesn't know if she'll be able to do parallel park or not. She took a course at the Florida Traffic School even, she said she was so embarrassed when she drove past a boy she has a crush on and she is in this dorkmobile with the student driver signs all over it.
I am reassuring her she will pass, everyone passes right? Well apparently, 2 of her friends had to take it twice. So either the test has gotten hard since I took it, or she is hanging around with some real idiots. If you fail it, you can go to Florida online traffic school, do their course, and take a written test online.
I personally think 16 is too young to drive, I think it should be 18. Of course, I did not think this until I picture my sister out there on the road cuttin' off blue-hairs in Florida. But 16 just seems SO YOUNG. If we had better mass transit in this country, it would not matter, but to ask a person to wait until they are 18, it is really difficult, we have jobs, we have a social life, we need to get around and can't be 17 years old with our parents driving us around.
