One suggestion is that the series may try the same approach used by the DRS system in F1, which only allows the rear wing flap to be activated if the car is within a certain distance of the one in front, meaning that for most of the race the system can only be used for attacking and not for defending.
"We built into the [push-to-pass] system the means to do just that," suggested IndyCar's vice president of technology, Will Phillips.
The main overtaking opportunity at Mid-Ohio is the Keyhole, a long straight after the exit of turn 2 into a looping right-hander turn 3. But the length of that straight - almost half a mile - could see drivers accidentally eat up their push-to-pass allocation faster than they were expecting.
"These straights are pretty long so 100 seconds goes by quickly," said championship leader Ryan Hunter-Reay. "You just have to use it when you need it, and it's tough to say when that is. Only in hindsight can you determine if you used it correctly.
"It's always a trade-off at the end," he added. "You're trying to make up time either catching a car or trying to get by somebody. You need it at the end to fight it out when the tires are going off so it's tricky."
Practice for the Honda Indy 200 gets underway on Friday afternoon at 2pm local time (7pm BST) at Mid-Ohio Sports Car Course with a 90 minute session divided in two, with 45 minutes for rookies and those outside the top ten in the championship standings, and the second half for all cars.
Another 60 minute practice session on Saturday morning at 8am (1pm BST) is followed by qualifying starting at 11am (4pm BST), with the track aken ver by the American Le Mans Series for the afternoon. A half hour Sunday warm-up session at 8am sets the stage for the race itself, starting at 1pm (6pm BST) and shown live in the UK on Sky Sports.
