I have been to 150 mph years ago when I could do it and it was many hours per year over 15 years or so. Another two cars I have now are electronically limited to 155 mph. The more powerful one I have had briefly up to 150 and it was a piece of cake. The less powerful one I have had up to 140 mph and also a piece of cake.
My old car was a 1986 Porsche 911 Turbo and it could be a handful. At 150 in a straight line it was not so bad.
In the 70’s I had a blown gas altered car. More recently I wen’t out on a friend’s Hayabusa, which had more speed in it than I managed.
