Was I wrong to ask my mom this?

I'm 16. I have only had my driver's license for a couple of months. Two weeks ago, I got in to a car accident that was 100% my fault. I was driving carelessly and backed into an oncoming car while getting out of a parkin. I was driving my mother's car reasonably new 1 year old or so. I apologized to the old lady that I backed into and told her how stupid and careless I'd been. She was nice about it and after the police came and got the details we both drove off. I felt so guilty, I can't really explain it very well. I just felt like I deserved to be ed. I had only ever been ed on maybe 3 or 4 occions, all of them occurred when I was a 4 to 8 yr old boy. My dad didn't believe in it and he ped away when I was 10. My mom would but only if all else failed, I guess you'd call her a last resort spanker. The accident gave me that same type of guilt I'd had when I'd been a really bad six year old. I was angry with myself for a lot of other things as well. I had once been an excellent student, but I was becoming lazy and despondent. I was a jekyll and hyde type of character at that point in my life. I'd have these moments when I was a typical rebellious disrespectful teenager. Then I'd have more reflective moments and I'd realize what a jerk I was and I'd experience a lot of guilt with how I'd treated my mother. Despite this my mother was always there for me and I knew she was doing her utmost to try to get the best out of me. Anyway I arrived home and explained to my mother what happened, I apologized and confessed that the accident was my fault. She was just happy that nobody had been injured. I told her I still felt guilty, but she just tried to support me. I told her that she should be upset with me, not just because of the car but because of how my grades had been dropping and my attitude towards her and others was disrespectful. I said I feel like I deserve a good . She gave me a strange look and said I was too old for that. I nodded and told her I'd be in my room. A few hours later she knocked on my bedroom door. I let her in. She asks me if I'm upset with her because there is no discipline in my life. I started talking about how when I was a young child I knew I had to achieve. I knew my parents wouldn't settle for half efforts and I wanted my life to be like that again. It seemed like after my father ped away I was slowly but surely getting lazier, less responsible and disrespectful (occassionally) to those that I loved most (like all teens I suppose). She says she understands the disrespectfulness, that she was a teen once etc. And she stated that at least I have a conscience and can admit my faults. She then asks me whether I think a will help me overcome my guilt. I told her it couln't hurt and that I need a fresh start. She says okay take off your jeans and underpants and I'll be back. Yikes, I get kind of anxious, nervous. Anyway I remove my clothes and lay face down on the bed. She comes back with an oval hairbrush and starts smacking me. I was trying to be tough and I was for the first 40 or so spanks. But my bottom became hot and sore and I began to sob quietly. My mother continued but slowed down and gave me another 20 or so. She then put the brush down and started to rub my back and told me that even though I was was far from perfect, I was still better than just about any other teenager she knew. I hugged her and vowed to get my life back on track. The following week-end I cleaned out the basement and started to do more chores around the house. Was I wrong to ask my mom to spank me?
