One of the things I enjoyed most about Colorado were the twisty canyon highways and roads, and it didn't take long for me to realize that on a two-lane divided highway such as I-70 there's technically nothing preventing me from hitting the apex on one of its many sweeping curves when the road is empty. But should I?
Sure, there's no risk of hitting oncoming traffic since the road is divided, though depending on your speed and the angle of the turn you might have only a very small window to react to a slow-moving or stopped vehicle just out of sight (especially if you're dipping into the right lane) But if we're limiting this to divided two-lane highways, that's about the only real danger I can think of, and it's not that significant when you can go a long time without seeing another car in many parts of the west. If there's no oncoming traffic and the road is clear and you're sticking to real legal surfaces (i.e. no shoulder), what's the problem, right?
And yet, I don't know, I feel a little guilty about the times I did it. I did see a few other people who always switched into the inside lane on curves, but it always more looked like discomfort with the outside lane than a deliberate racing move. The road isn't a racetrack, and I can twist the justification of "getting there faster" eight different ways and it still won't make sense when you consider that most of the world gets to where they're going on time without lane hopping like a yahoo. The other thing is that while every curve has an apex, on a public road those apexes don't necessarily add up to an enjoyable or safe racing line. They built roads like I-70 in Colorado to require the least amount of earth-moving possible, and while the result is some pretty fantastic curves, those curves are incidental. They're not really a design feature. So when you hit lines that allow you to maintain a speed the road makers never intended, it's possible the next curve could actually be impossible at the rate you're going. Hopefully you are good at braking.
So I guess my position can be summarized as "it's obviously fun and awesome, and seems like a victimless crime, but don't get carried away." Your thoughts?
