Collection: Mario Kart

In 2016, Nintendo entered a legal dispute with MariCar, an Osaka-based company offering tourists Mario Kart-themed tours of the city using modified go-karts. The service included costumes based on the Mario Kart roster and alluded to the games' items in its advertising, jokingly asking customers not to attack each other with "banana peels" or "red turtle shells." Nintendo filed a complaint with the Japan Patent Office in September, arguing that the company's trademark was deliberately over-evocative of that for Mario Kart. Four months later, however, the office denied Nintendo's request, noting that "MariCar" was not a common abbreviation for Mario Kart, and thus the two trademarks did not conflict.

As the Japanese legal system does not include fair use protections for parodies, Nintendo subsequently sued MariCar the following month for copyright infringement due to the unauthorized inclusion of Mario character costumes. The case was ultimately decided in Nintendo's favor in September 2018, with MariCar being forced to drop the Mario Kart iconography and pay Nintendo ¥10 million (roughly equivalent to $89,000 USD) in damages. The company attempted to appeal the case to the Japanese Supreme Court, who rejected the motion in December 2020 and increased the fine to ¥50 million (approximately $483,000 USD). MariCar has since rebranded as Street Kart in the wake of the lawsuit.

According to Tesla CEO Elon Musk, a Mario Kart game that could be played while inside their cars was once proposed to Nintendo, only to be turned down as they refused to license the series to Tesla.

A 2016 study conducted in Hong Kong revealed that more players drove a car better after playing Mario Kart. This was because “easily accessible action video games for as little as 5 hours can be a cost-effective tool to help people improve essential visuomotor-control skills used for driving,” according to the Association of Psychological Science.

Mario Kart: Super Circuit is the first game in the series to feature a Lightning Cup. It is also the only Lightning Cup with original stages, as from Mario Kart DS onward, it only featured stages from previous Mario Kart games.

In the Mario Kart games, Rosalina is a heavy/large class character. However, in the Super Smash Bros. series she is a light class character. The reason she is a heavy class character in Mario Kart is most likely due to her height.
