It’s pretty easy to do a sustained 120 mph in a Honda Accord for several hours on I-71 through Kentucky. (Not personal experience.)
A Toyota Prius can maintain ~90 mph on I-294 around Chicago. Anything above 95 mph degraded the tire traction to an unsafe level. (Personal experience.)
I don’t do that much anymore now that my manic episodes are under control and I’m better able to recognize my judgement is impaired.
I actually have to set up a car alert for when I go above 90, because the car is so quiet and powerful that I can easily go above 90 without realizing (obviously on the highway) .
New cars have improved tremendously.
