Should I buy a new car?

I was late for work and wanted to not be totally late so I drove ridiculously fast. It was early so very dark. I underestimated an S shaped curve in the road and went off the road into low water at 60mph. Paid 2k for the car and just bought it 2 months ago. I'm 18 and ashamed by my behavior. Long story short the car was totaled and had a friend tow it away for free. It was a serious accident but only had a swollen knee. Could not get my door open so went out the passenger door up a 6ft mud and grass slide. If I had been able to make the first turn I would have went off the second turn before this small bridge into DEEP water! I would have died in a flipped car in dark water leaving behind nothing but hurt to family and friend. I now have 2k in the bank and if I buy another car I will have 1.5k by march at which point I wont use my car as often. I have no valuable education and no chance of a Job. I live on a tiny boat because my mother kicked me out 3 months ago. I have a motorcycle and can get around cheap and still pickup my friend every day. Whoever, I WANT a car! It's not responsible but I could have died today. Why not enjoy my money! Plus I will never go over the speed limit again! I feel kinda shocked. So... Yee or nee on the car?
