What to do !, my dad is killing me ... Options

[NaderG]

So i tuned 18 like a month ago and i can actually do stuff without needing parents signature... i wanted to get a bike so i went ahead bought some ride gear , signed u for a motorcycle safety course for which is really really good and i recommend it to those who ride but learned on their own .... anyways , my dad found out after i went for the first session in the course and is against the idea completely ! he said to forget about it and not even bother finishing the course and even return my gear and stuff.... i tired explaining how it can be safe depending on the driver( he thinks i am an insane driver because he drivers slower than the average grandma while i am a bit more spirited) and the techniques plus i am planning to buy a pretty slow bike ! ( GS500F ) .... he is also against me customizing the car in any form , he is against engine swap, lowering and what not ..... so what should i do ?????
Things i need to mention :
1-i cant move out ... i from Egypt ( probably only Egyptian with a 6gc woot!) and as culture dictates , it is not so ok to move out
2-Even if i moved out because of school or whatever, i still have to get his permission for everything ( culture too)

So ya , i am pretty much screwed ....... uh , i just needed to rant !!

thanks if u bothered reading this
