From your post it would appear to me that you are going to be a safe and reasonable rider. Good for you.
The problem (as already pointed out) will be the other people on the road. The idiots. They are out there, I've seem them, so has your dad. Guess why he doesn't want you out there. He doesn't want you dead.
I took the MSF course years ago when i got a bike. A few years ago I had my son (16 or 17 at the time) go thru the course. Not because I had any intention of turning him into a biker, I just thought it would be a good "drivers ed" course for him. He begged and begged to ride my bike so I started letting him ride around the lot at work (huge) and made him practice turns and sudden stops a hundred times before I ever (finally) let him on the street. He dumped the bike one day, didnt tell me about it and I never let him ride again. I don't want him dead.
If your dad still rides, here is what would work for me:
1. Buy the bike and pay for equipment, registration & insurance.
2. Agree to ride only with your dad following (each on your own bike) until you have demonstrated that you are safe.
3. Agree to let your dad give you his own version of a riders test before turning you loose on your own.
4. Listen to his advice. Try his suggestions. Benefit from his experience. If he gets the idea that you will do things the way he wants, he will feel a lot more comfortable about you riding.
5. Don't ride at night except maybe around the neighborhood on streets you know like the back of your hand. (I love to ride at night and I'm a lot more visible because of the lights but unfamiliar roads, potholes, dips and other surprises are bad on a bike)
Don't push the bike thing for a couple weeks to let it cool down and then hit them with your proposal. Agree to let them "ground" your bike if you get a ticket or do something stupid. Good luck!
Domi: Love your answer -but- what happens when his folks tell him to ask Bruce over for dinner?
