The terms and conditions keep applying. The everyday real world conditions implied by "highway speed" include regular cache misses and branches.
It's not about "start" or "acceleration". This massively impacts the steady state speed.
If you want a car analogy, tight vector packing compares to normal code about as well as looking at the speed and width of the flame front across a cylinder and using that to measure fuel consumption.
