Well it's not currently legal to ride on freeways, and there's not much point anyway, except in places like Colorado where they are sometimes the only route across the mountains. The whole point of freeways is that one can travel at high-speed, and you're not reaching those speeds on a bicycle. That said, if we stopped wasting time, money, and lives on building ineffective dedicated cycling infrastructure, and instead fixed the actual problem of road user behavior, those interstates with their tremendous sight lines, slight grades, and wide shoulders would be perfectly safe to ride, and would open up a whole new class of bike travel -- almost for free.

But who wants that, right? Let's instead continue to throw away time, money, and lives on construction that has never worked yet, anywhere on the planet.

The pride in ignorance exhibited by many here is alarming, and sad. I did not expect to find that bikeforums.net was a harbor for so much of the internet's anti-intellectualism and anti-education sentiment.
