If you come at a complete stop anyway, it's fine with me. Bikes can't accelerate all that quickly, so it ends up being pretty slow traffic.

- qubex 4y ago> Bikes can’t accelerate all that quickly Interesting statement. Do you have some data? I’ve often mused anecdotally that the initial acceleration from the first pumps on the pedals give a pretty abrupt change in momentum.
- unsafecast 4y agoI don't. I just compared my perception on how I and other people accelerate with the width of the road. Intuition tells me it's not dangerous (of course, assuming everyone is responsible). Now that I think about it, it depends on a lot of factors. I don't know how the roads look in Idaho, but I assume they're much wider than where I live, which gives you more time to get up to speed. I haven't considered e-bikes either.
- MisterMower 4y agoYou shouldn’t need data, it’s common sense. How long does it take a car to go from stopped to 30mph? Five seconds? How long does it take a cyclist to go from stopped to 10mph? Certainly not less five seconds. In those scenarios, average acceleration for the car is 6mph/s, for the cyclist it’s 2mph/s.
- qubex 4y agoAs you say so yourself that’s average acceleration. No contest there.
- MisterMower 4y agoWell you don’t know the difference between momentum and acceleration so I figured I’d walk you through a little thought experiment. Sorry you didn’t find it helpful!
- qubex 4y agoI don’t know the difference between [difference in] momentum and acceleration?? Says whom?? Δp=mΔv=FΔt
- falcolas 4y ago> Bikes can't accelerate all that quickly E-bikes are changing this dynamic pretty quickly. And unpredictably. They can get from 0 to 20 faster than a car.
- unsafecast 4y agoYes, I hadn't considered e-bikes when I made that comment. Definitely changes things.
