So those roads would require lower speed limits?

  Most of these kinds of roads do have low speed limits (especially around "blind" corners). The problem is, drivers feel confident traveling at speeds higher than the posted speed limit. Roads need to be designed better so that the speed limits more closely match speeds a normal human would feel comfortable driving. Narrowing lanes is one trick for accomplish this.

    Yeah, it's less speed limits and more that people don't leave proper following distance. Most people leave 1-2 car lengths yet even at 40mph you'd need to leave 3 cars not to be kissing bumpers(40mph = 60ft/sec, 1/2sec reaction = 30ft). I don't brake for small animals on these roads for similar reasons and I've lost count the number of times I've had to dive for the shoulder when someone overruns their stopping distance behind me(which is why you should always keep an eye on your rear mirror in a panic brake situation). Intentionally biking on these roads put everyone at a higher risk of these types of situations happening and a bad outcome for all because of it.

  And then they'd be even more dangerous since you'd have fast cars vs slow cars vs bikes instead of just fast cars vs bikes. People don't follow the speed limits. They optimize for a constant amount of risk. Depending on conditions that's 20-over or 15 under or anywhere between.
