It is .my impression that the vehicles were entirely on their own without any human control. Very impressive, especially the fact that they found and "crossed" the finish line. And if I have the opportunity to cash in my pic chips here in California, I would seriously consider living in Costa Rica. Is broadband internet connection available there? Would my dog Pookie be welcome? And if so (concerning the local wildlife) what would be her position on the food chain?
