If going downhill, revv will be lower if you're taking ur foot off the paddle.

Always use this route to go back to my hometown. Wouldn't recommend anyone to go fast like this idiot driver does.
Endangering other drivers along the way.

On the side note, the part where he reaches 200km/h is going downhill and if you have the guts, most cars can reach that speed. It is possible even with a Viva and a strong heart.
