The act of speeding just after escaping from an area of dense traffic. Flooring it after you pass the car in front of you often leading to speeding tickets or warnings.
"Jim got pulled over yesterday for freedom speeding on the freeway."
"Freakin cop pulled me over when i was only freedom speeding for ten seconds."
A person in control of a motor vehicle who is merely going through the motions of driving. Generally unaware of the situation around them, their mind likely not focused on operating the vehicle. Typical symptoms include driving slow in the left lane, tunnel vision, and being on their phone.
This idiot has been going 50 mph in the left lane for the past ten miles, he’s clearly just a steering wheel holder.
When you're walking/riding/driving so slow that you get aggraveted by the situation, so you say "I'm speeding like a plum!". Since plums can't speed at all the direct meaning is contrasted in a sarcasticdefinition, emphasized as going so slow, almost stopping.
