This is really cool; I'm glad to see this kind of technology reaching younger students. In grad school, we actually built something similar for undergrads to use as part of a robotics course. The idea was to give teams an identical platform, and then race them at the end of the semester to see who did the best job at programming it.

If anyone is interested, we open sourced all of the design files, with instructions on how to build a car of your own for around $900 (at the time, this was several years ago): https://vaderlab.wordpress.com/roscar-robot-stock-car-autono...

Here is a video of the results from the semester. One group was able to max out the speed on the car, which at scale is equivalent to 128 MPH: https://www.youtube.com/watch?v=jwRjv3D7lGo
