Formula 1 is arguably the most-watched car series in the world, with 425 million estimated viewers last season. It also has some of the most expensive cars in racing, with each car worth around $2.6 million.
It also has some of the most high-tech cars around with computers that control and monitor every aspect of the car, from engine performance and airflow to tire degradation. Any one car can have from 100 to 300 sensors with the number changing for each race.
The information the computers collect is sent in real time to the pit crews and engineers using trackside antennas so they can analyze the car's performance during testing and during the race. As an example, The Lotus F1 team has its own setup of 50 virtual servers at each track that pulls in and processes 30 megabytes of information per lap.
During testing, the teams can use the information to tweak the car to match the track. During a race, they can instruct the driver on setting or driving style changes to make the car perform at its best or compensate for problems.
Unfortunately, those computers open up the Formula 1 cars to a serious danger. According to security experts, Formula 1 cars can be hacked.
