In another example Formula Race Car driving needs special road with high security such as medical team and high speed car maintenance, consequently the general people who like this type of sports cannot do it in the street with a simple car so it needs a lot of money to buy special car. Although this type of sport needs strong financial support by companies or governments.

Many sports have the same situation so people prefer to watch them from TV because this athletic activity needs much money, in addition some of them needs proficiency; sometimes watching football competition between professional football teams is more enjoyable than play in a small football court, without any observer. For example I am a junior tennis player and play every odd evening, Always I watch tennis completions from TV consequently it lead me to correct my tennis style by following their playing.

Today we have lots of sport and some of them are not accessible for general people consequently the people prefer to sit in front of TV and watching these sports without any cost.
