A really common sport that quite a few people decide to take part in on a more or less regular basis at this current point in time is racing. While historically racing was done on foot or on horses or perhaps even horse drawn vehicles such as chariots, in this modern day and age there is a wide range of racing sports that involve the use of cars since these vehicles are arguably the fastest objects that people can travel in while they are still on the ground without a shadow of a doubt.
As a result of the fact that this is the case, sports like NASCAR have achieved worldwide popularity due to the extremely high speeds at which the cars participating in said race tend to travel. If you want to know just how fast these cars go, the answer to your question is around 200 miles per hour which can also be described as 320 kilometers per hour. The latter comes from the metric system which is a much more reasonable system of measurement that can be extrapolated using simple numbers instead of advanced types of calculation.
Suffice it to say that these speeds are so high that NASCAR drivers usually need to undergo years of training before they can take part in these races in a manner that is as safe as possible. It can be difficult to maintain control of your car when it is driving at such speeds, and trying to get to even half of these speeds will most likely result in you crashing your car. NASCAR uses special race tracks to improve the safety of the drivers that are involved in it.
