i will point out some of the details for people who didn't want to read it.
the car weighs 10,000 lb making it almost undrivable, there is minimal room for the driver, the system does not have a stereo because its only designed to play a single tone. some of the cars have 2 inch thick glass, and bolt the doors shut, others have filled the doors with concrete. the system is so load that you can't be in the car when it is running so everything is done remotely with the car sealed shut. the speakers used are designed to only play this one tone and are not capable of doing music, they also burn out after the 2 or 3 seconds of use and most of the time is spend replacing the burnt equipment during runs. the final competitors go head to head in an all out system melt down in which the person who hasn't fried all the tech wins. its expensive, just to produce a tone you can't listen to because its too loud.
if this was about loud music, or high quility music, or install design, i would be happy because it has a function, but to play a tone til all the equipment is fried seems pointless.
i know everyone has their hobbies and often if you are not into them then they seem pointless, but this is like burning money
