It seems that most of us agree that whether you are doing 250kts or 350kts or 100kts it makes diddley squat difference when it comes to actually having the luck and the time to see someone and take avoiding action when solely relying on your eyes, your crewmembers and in a lot of cases some poor fellows eyes in the control tower. So it seems odd saying that the 250kt rule makes sense, when nearly all mid airs occur in the circuit and at far lower speeds. What if I'm doing 251kts? Is that unsafe. Or 230kts? Ok, so it's the law, but the law has been proven countless times to be an ass in many cases. Is it so in this case?
And should gliders and micro lights etc have transponders?
