Thank you for your reply.
Maybe, one day, I'll try again. For now I cannot afford my own car anyway and I doubt if I will in the near future. My father's car is 20 years old, an old bmw, that's almost falling apart and I don't really wanna drive it, because he wouldn't forgive me even scratching it, there's always some trouble with it, especially the cooler, and I convinced him that I cannot drive anyway (I was driving with him a few times). The car is pretty long and wide and that's not good for me either. Most of my friends had their cars bought by their parents, they're paying for everything, I can't have that. It would be easier to have an automatic transmission (Most people in my country drive manual, automatic cars are pretty costly) and - my dream - a new car with this posibble crash sensor, but I would have to get rich. Yet the biggest problem is not the car, but the constant need to process the road in a right way and constantly changing enviroment.
