I assume they can get to medics at the pit stop.
As for cameramen fallling over, if you have seen other series you would know that sometimes they encounter "production difficulties" that give them time credits.
I thought the team of cousisn (with the little person in it) was annoying, simply beacuse that kept on saying "why is no-one helping us". No-one is helping anyone, it's a race, get over yourselves.
That trick with he planes was mean, but good. And two equlaisers in the first leg, interesting.
The "yeild" sounds like and interesting concept, but I hope they havn't ditched roadblocks or fastfowards. I am curious to know what the suprise difficulty is that befalls those last to non-elimnation pit stops.
Lastly, there seems to be a lot of ways in this series to make teams fall way behind. That seems like a bad idea on the production comapnies behalf, you want close finshes at every pitstop ...
