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

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.
