Regarding R&A not stopping when the brothers car flipped: When I first watched this I thought that they could have at least asked if everyone was ok and then kept going. It should have been obvious that they would have finished at least before the brothers. Now that I've had time to think about it some more, there were other people already there, Lynn and Alex stopped so they were there plus their camera crew. Their camera crew were the ones filming the others as they came upon the accident and filming what was happening. Therefore if someone was really hurt I doubt everyone would have been standing around like they were. So when R&A came upon them they did slow down but kept going after seeing everything.
I've been of fan of AR since the first season and I haven't decided on who I'm rooting for yet. I did like the brothers and was sorry to see them lose.
Also to be taken into consideration is that we only see what the producers want us to see. Most of the participants are shown the way they are, but because this is a race and they are deprived of sleep and food and in unfamiliar places, you see a different side of people. I think that because R&A have been on a reality show previously they realize what effect things said can have. On the otherhand I saw that Ray and Deana are now engaged and after their last show who would have thought that? Ray and Deana both said that when it's not a Race type of competitive situation that Ray is a different person.
I wish that the show would have a clock so that we could see how long it takes to complete tasks, how far each group is ahead or behind, etc.
