Definitely very interesting. Thanks for sharing. I agree that it's scary to know that at 40+ mph you're pretty much a goner. I too ride on roads with high speed limits - often 70+ (and in west Texas that means 8- mph+). Luckily when I commute in the morning the majority of it is through a nice little neighborhood and I only have to ride on a 45mph road for a little bit. But then again, I'm pretty fearless.
