Some famous physicist, I can't remember his name right now, once said, "it's all relative!" You absolutely have nothing to support your claim of 1sec difference 0-150 between the E46/E92. It's simply dillisional to think that it's only 1sec 150mph.
Second, not sure why you are bringing in 0-60 and 0-100 data to make your argument to me. There are many cars that are fast to 60, some to 100, but stretch it out to 150 and it really starts to separate cars from the rest of the pack. My whole premace and original point/post was every generation the performance gain gap got bigger from the previous generation, with the M4 we will definitely see substantial gains but nothing like what we saw with the E46-E92.

Boss' physics are correct. The 1 sec time gap in the 0-1000m does translate to an approximate distance gap of 66m for cars traveling around 150mph.
Assume 2 cars both travelling at 150mph with one of them 1 sec behind the other one. You are standing still on the side of the road at the 1000m marker. The first car passes in front of you. You wait 1 second and the second car passes in front of you. At that moment, since you are standing still, the first car has traveled 67m in that 1 second time and is now 67m away from you. Hence the 67m gap between the two car. This remains approximate because after the standing km, the first car is still accelerating and is not travelling at the exact 150mph speed. But 66m is a fairly decent approximation.
You cannot compare time to speed and time to distance. A 1 sec difference in the 0-1000m has no direct correlation to the 0-150mph time. For example, if a car is faster by 8 seconds to 150mph, in no way does not imply that it is 536m (8sec x 67m/s) ahead of the other one.
0-60mph and 0-100mph are important because the faster a car accelerates in the earlier portion of the run, the less time it will need to travel the entire distance, even if both cars have the same trap speed at the end. A car could even be slower to 150mph but still be faster to 1000m. It is the same logic as with the tradeoffs between ET and trap speed for 1/4 mile runs.
