Kevin Harvick and Matt Kenseth are both concerned about how quickly ambulances have reached the infield to assist drivers this year.
Kenseth was actually involved in a crash due to an ambulance stopped at pit road, and he cited two instances where ambulances weren't timely in reaching him this year.
"I think it was actually the spring Richmond race," Kenseth said. "I was (riding) around the infield for about five minutes with him and he was lost and couldn't find the infield care center, so thankfully I wasn't bleeding to death.
"Then the other one, it was after California or something like that, he drove so recklessly it threw me off the bench and I almost hit my head in the ambulance, so yeah, there's been a couple of instances this year actually."

Harvick said at playoff media day that the ambulance issue has affected several drivers this year.
"The ambulances, for whatever reason this year, have been a little more of an issue as far as getting to the accident, getting back from the accident (and) getting lost in many circumstances going back to the infield care center," Harvick said.
"That's been an issue not only for myself, twice, but several other drivers as they've had their trips to the infield care center. I know they're continuously working on trying to make that better. But the ambulances need to know where they're going."
Denny Hamlin cited Aric Almirola's injury as a time where the ambulances were too slow, which was a major issue considering the seriousness of his injury.
NASCAR officials said they are working on the issue as several drivers have raised complaints this season, so hopefully they can fix it before there is a serious issue in the future.
