Not sure. But it does say this underneath the upper playfield area:

“Full throttle... ignore the wall”

I found this from a google search re: the throttle...wall phrase on the playfield:

“About that [phrase]. It actually has a double meaning. I don't think Pat has ever discussed it.
First one was that Pat is a big NASCAR fan (we were trying to get that license even back in the Williams days). So that's an obvious one. Pedal down and turn left!
The second one was a dig at Williams management. Pat had tried to reason with them to not overproduce games and/or stuff them down the throats of distributors. Forcing weak games on customers and stuffing the pipe was bad for business and things had already taken a serious turn for the worse business-wise (and we were still a full 2 years before shutdown).
IIRC, the conversation with management was "if you don't slow down we're gonna hit the wall" and the reply was "f* it, full throttle!" This is why Pat hid that text in the back loop where nobody would really see it.”
