What can one do about it? The ambient temp was only 75F and I will be at VIR in another month where it will likely be 85F!

Take some fluid out of the fluid reservoir.
E39 M5's had the same problem and the cure was to use a turkey baster to lower the level by about 1/2" in the reservoir. As PS fluid heats it expands and it has to find a way out. Lowering the level made more room for expansion and the problem went away.
Before anyone starts advocating for synthetic fluid, the M3 comes with synthetic fluid already.
