I was pretty eager to get mine, and my parents pushed it hard, as well.
Of the three amigos (there were three of us that stuck together throughout HS) me and Ashley had our licences ASAP. My birthday came early, so I didn't get mine until I'd been 16 for a few months, due to the Drivers Ed program not taking sophmores in the fall session unless the juniors hadn't filled the slots.
We both had junker cars, my first car was a $500 wonder (mercury Lynx), and the second was a Chevy Cavilar that was older then me. Ashley went through two (?) Cougers, through HS. Our parents would cover most the costs.
My mom was about sick of driving me back and forth between her and my Dads house, sick of activities, and the bus ride to and from school at her house was over an hour, so I hated riding the bus from her place. Dad didn't like it much better.
Beanie, on the other hand, still (i think) doesn't have a licence. She had a learners, but driving freaked her out. It didn't help that a girl she had been BF in elementery school with died in a really bad wreak leaving school one day. The other girl was paralized. Beanie was also always in the car when me or ashley got into acceidents (i only had one!) Which probably didn't help.
Most kids at my school were pretty keen to have a car, but there were plenty who did without. I can see not having intrest if you live in a city with good mass transit, but, even with the rising prices, I can't see how others in more rural areas wouldn't want it. Even if the kids don't, the parents who have to drive them all over for activities would.
