Alright, I feel the need to defend meezy here - I don't think you need to have direct experience with the disabled to comprehend the situation. Does it help? Sure, but it's not necessary. I feel that Luke is being given a little bit too much of the "aww, he's deaf" treatment here. He's not a bad guy, but he does show overcompetitiveness and a bit too much intensity at times. I don't remember the quote, but there was something along these lines in the first episode when Margie was driving that ticked me off a little bit. I know I sound lazy, but I don't feel like re-loading the episode just for the sake of this post.
I don't think the novelty of being deaf is as high as it normally would since I did watch the episodes of TAR:Asia online and Adrian pulled through the race perfectly fine.
