However, it's worth noting that there were other contributions and concurrent developments in the creation of similar rides. For example, a patent for an electric amusement car with a buffer mechanism was filed in 1921 by William H. Riley. Additionally, various amusement ride manufacturers and inventors experimented with different designs and improvements to the concept over the years.
In summary, while Max Stoops is often credited as the inventor of bumper cars, there were likely multiple individuals and companies involved in their development, making it challenging to pinpoint a single inventor.
