Okay, you should have said that in the first post. If you're not using the class of vehicle the comment was talking about, your experience isn't really relevant.
Even so, I can go at least 4MPH greater than OP's suggested maximum speed legally.
We know :)
(to be fair and charitable: I agree that moving with traffic is, everything else equal, safer than not moving with traffic. But everything else is NOT equal - I am not convinced you have the weight [i.e. centre of gravity, inertia, ability to absorb bumps, etc], maneuverability, traction, braking power, and as you point out insurance or license and possibly training, and possibly protective systems as other vehicles moving at the same speed)
2) "Moving with the speed of traffic for my safety" is a... "Nice" (that was sarcasm, I mean egocentric) attitude.
3) "The speed of traffic" may be higher for you now that you live in the countryside, but A) sounds like you rode / ride about as fast in the city, too?; and B) the typical use case relevant to the discussion is not yours but the city/suburban one.
It's bad enough that you can go so fast indefinitely; please don't.
Yeah, that is the legal limit but I turned it off in the bios. When cycling on roads I want to be going as fast as possible to keep things safer for me by moving at roughly traffic speeds and disincentivizing dangerous maneuvers by motorists. On bike trails and such I keep to 20mph or so as safe.
I actually tried to get mine registered as a moped with a license plate and insurance coverage etc. but was essentially told to take a hike by the state and insurance companies. So I did.
