I am sorry if what I am about to say is out of line, but let me understand this. You are about to have an operation on your hand that could leave your arm with no feeling. Your brother, your next of kin, your blood, is going to drive you around and because he doesnt like your car you trying to upgrade? Firstly this is about you, your comfort and your welbeing, not his. If he were my brother I'd punch him hard with my good hand and tell him to wake up and remember why he is doing this.
On another note, you say that you may lose the feeling in your arm, I dont know the rules but losing the feeling and driving but the op doesnt stop you using your arm and hand does it? So there must be a solution that the brains on this forum can suggest.
Again I am sorry if I am speaking out of turn but we see so much suffering in this world that it just irritates me when I read things like this.
Said my peace I'll shut up now.
