It was.
See, speed takes on a number of forms, not just going over "the limit". Speed involves hurriedly turning in front of people on bikes who have the right of way because you're too impatient, or in too much of a hurry, to wait for them to clear. Speeding is when you're operating a vehicle in a capacity where by virtue of the way you are operating it (your inputs), you are not able to control and account for all of the outputs.
If it distracts from your ability to fully and absolutely control your vehicle, you're speeding. Drifting into the bike lane at 35 because you're texting? Three times the legal limit making it hard for you to distinguish taillights from stoplights? Distracted while you think about that trivial fight you and your SO had that caused you to "go for a drive to clear your head?" Road raging because the guy in front of you is ambling through the rush hour intersection meaning you're gonna have to, UGGGGH...wait...ANOTHER SIXTY FUCKING SECONDS FOR THE LIGHT TO CYCLE SO YOU CAN CATCH BACK UP TO HIM AT THE NEXT 500 FEET AWAY AT THE NEXT LIGHT!?! ARRRGGGGH!!! Yeah, that's speeding. Those are ALL speeding.
Why? Because you need to slow the fuck down. "Slowdown" doesn't just mean "Stop Speeding"; it means, "Stop Driving without due care and attention". Further, it means, "don't drive in a way that endangers the safety of persons or property."
Speeding isn't inherently dangerous, driving recklessly is; as such reckless driving seems to always involve some element of speed, be it operating over the limit and being distracted to a degree that you can't respond in the time that is required, or some mix of the two. By extension people use "reckless driving" and "speeding" interchangeably to refer to the same concepts and themes.
