One thing I noticed about driving really fast in a car, at least for me, is that you get into a state of almost hyper-focus. All your senses are hightened. Feels like your entire purpose of existence at that very moment in time is to be one with the car. I think if you are driving really fast and feel very unsafe, you need to focus harder!
I've also noticed that after doing 240k/150m, doing 110k/65m on the highway feels really slow now
