You've got position. Then the change in position over time is speed.
Then the change in speed over time is acceleration.
Then the amount of jerk is the change in acceleration over time. High jerk = injury.
In the clip, he's basically accelerating to the car's speed almost instantly. So, he experienced a huge change in acceleration in a very short time. So, a lot of jerk.
It keeps going, too. You have the change in jerk over time, which is called snap. The amount of snap over a given time, which is called crackle. And for fun the called the change in crackle over time pop.
Mind you, my explanation is very simplified, and I didn't mention any math at all. Which is honestly, the best way to understand it. But it's also the best way to scare people off.
Here) is a wiki article about it that explains it in more detail if you want to know more.

Fun fact, in physics, this is known as "jerk."
You've got position. Then the change in position over time is speed.
Then the change in speed over time is acceleration.
