Not really AFAIK, since it's an asymptote regarding your speed vs speed of light, so it's a pretty continuous curve. The point where things become weird is at close to the speed of light so in your example at like 1.9~1.999 m/s, and physics "break" at 2m/s, but there's not a sigle point between 0~1.999 where anything "surprising" happens.
I feel like your field of vision expanding and everything around you freezing might be considered surprising. These don't become noticeable until near the top end.
Yes but I purposefully used "a single point" in my phrase; since this phenomena doesn't happen in discrete steps, but in a continuum.
Things get "weird" non uniformly at all the various fuzzy intervals where the effects of relativity are significant in scale compared to the measurement error, in time and space dimension, of whatever phenomena you are studying or experiencing. There are many of these phenomena at different scales, and which ones you care about is subjective.
Could we create a vacuum tube and accelerate macroscopic objects in this tube close to the speed of light?
Our best effort so far: https://en.wikipedia.org/wiki/Large_Hadron_Collider
Note how big large particle accelerators are, such as the LHC, and that only gets a proton up to 99.9999991% c.
