The technology is getting its first proper shakedown at the Mid-Ohio race on August 2nd (today, if you're reading this in time) at 1:30PM Eastern. However, some teams already see potential problems. While the LED array is only 0.11 inches thick, it's still adding small amounts of weight and wind resistance to the car. There's also a concern that pit crews might be distracted with a display just inches away from where they're working. They may not have much say in the matter, mind you -- IndyCar is a spectator sport at its heart, and the sacrifices might be justified if they help fans make sense of vehicular chaos.
