When you are competing with the best, you need to be at the tough of your game because you would not last long if you are not going to do your best. That is what its like in car racing. You need to be at the top of your game or you might end up losing your life. There are lots of accidents on the road, but that can't be compared to a car race since you would be driving your car at the top speed. You need to win it not only to prove yourself worthy, but also to claim some bounty.
In this game, you need to win it to be able to get to the next level. Needless to say that the game would be harder as you make some progress. With the price money that you get, you would be able to buy some upgrades for your car. Fortunately, you have a little money to spare at the start of the game, which you can use to upgrade your car. Things won't get easier, so you need to drive fast and in control, so you can win the race. Being fast is not all about this game as you need to have the skills to win a race.
