Theoretically this would be true in a perfect world. Good god man have you been on I-25 lately? The cross traffic is the guy in the fast lane that needs to take the next exit. No one is going the same speed at all. I'm going 90 just to get the hell off that ribbon of death as fast as possible.
There are more idiots on that road than I have seen anywhere except Tennessee. Tennessee drivers are a special kind of idiot.
I'll take the canyons any day. At least the animals in the canyons are actually the four legged variety.
