It shows a lack of care for the safety of others. I'm not sure what the laws are where he got ticketed, but where I am, if you go 25+ over the posted speed limit, you get ticketed for wreckless driving. Going 40+ over the posted limit definitely crosses the line into being straight up wreckless.
Doesn't matter what time of day it is, or how much traffic there is, all it takes is something in the road that you didn't notice to cause you to slam on your brakes and swerve, causing your car to flip over multiple times, endangering yourself and/or any passengers plus any nearby vehicles.
