Miley Cyrus says her mom's black Porsche -- which she inherited around her 16th birthday -- was driving her crazy.

So she ditched it for a new set of wheels.

"I didn't like it 'cause it was bad for the environment, and it was too big," she says in a new video on her Web site. "My dad surprised me last night with a black Prius."

She likes it better because it's "good for the environment, and it's adorable!"

Her first item of decor: "I'm gonna get Hello Kitty floor mats!"

Cyrus, who turned 16 in November and recently obtained her driver's license, had been longing for her dream car for some time.

Last August, she told Radio Disney that she wanted a car that was "big enough for all my friends and to scare all the cars away from me. I'm a good driver but it's everyone else that I'm worried about!"

Oh, what a big thing to do! Toss away the Porsche for the Prius.

I'm sorry, maybe I'm being a big man-bitch here, but this whole article just sort of rubbed me the wrong way.

You know what my first car was? It was a big, gray station wagon that only ran once in a while. I got that when I was 20 because my mommy wouldn't pass down her old car to me. If she had, I would have had a Toyota Camry with no rear window and more rust on it than you could imagine. I seem to remember there being a clear bag as one of the windows for about six months until they could replace it, and that rear window was actually replaced with a piece of plexi glass from Home Depot.

Your own car at 16? First a Porsche, then a Prius? My God, I feel so bad for her. How could her mother be so cruel as to hand her a Porsche, as bad for the environment as it is and all? Tsk tsk. There's a hot place in hell for a mom like that! *insert eye rolling*
