This nameless vehicle from Roush Technologies is for training horses and camels.
It might look look just a big can, but this is a piece of high-tech machinery able to monitor racing animals at speeds of up to 60 miles per hour. The nameless vehicle has some kind of enclosure in front of it, resembling a horse starting stall, in which animals can walk and gallop while being monitored by veterinarians and racing experts. It has a centered seat for the driver and two more for a racing specialist and a veterinary expert. Onboard technologies include heart, oxygen, breathing and fitness monitoring to make sure they are in top shape for official races.
