Need For Speed

It seems that I'm always playing some sort of video game against most of my young cousins.
The game that enabled me to teach them a quick lesson on life is any of the Need For Speed racing games.

Money is earned after winning races.
After each race, my cousins would always spend this money on rims, paint jobs and tinted windows.
But they could never finish the game.
Their cars looked nice - but they lacked the speed and control to enable them to compete against the tougher competition in the more difficult races.
I would always buy tires, shocks, engines and then nitro.
My cars looked jacked-up but they were easy to control and fast.

When my cousins learned this secret - they immediately re-raced the older races (only getting a fraction of the money won in one's initial attempt) and started adding to their car's speed.
Their cars now looked nice and had a lot of speed.
But they would still lose races.
They had the speed and the looks - but they lacked control.
They would always crash into obstacles.
And lose races.
