Was reading this information
from here. Thought it was interesting.
-- An optional electronic cluster (digital dashboard) in the ****pit of the race car, increasing the information available to the driver.
Through the digital dash, NASCAR will be able to communicate to the driver, for example, the instant caution is called, as well as the driver's position in the running order for a restart. The long-term trend is toward enhanced data acquisition, Stefanyshyn said, but not at the expense of the driver behind the wheel.
"We always want the driver to drive the car," Stefanyshyn said. "We will be collecting data and harvesting data, not to be able to send to some central command station to tell the driver what to do with his car.
"We'll be harvesting and collecting data to officiate better, to inform our fans and provide them with a richer experience.
"One of my future goals would be, if we have an incident on the track, and we have a device connected to the driver, when you turn on the incident data recorder, that goes to NASCAR Medical, and they know instantaneously which car to go to first if we have an issue."
