If you have the power, you will use it! Pretty simple... It's normal, we are humans...
I think that the biggest factor of all is... LUCK! You drive like an idiot but maybe you got a 1A Engine. Maybe you drive like a grandma, but you got a piece of monday crap in your engine bay... There still are tolerances for our engines. Maybe you got lucky, maybe not...
This
applies when you're not a freaking idiot...
