Given a particular car/bike with a particular set of tires on a particular track, Newton’s laws impose a theoretical limit on lap time. I don't know how close

Given a particular car/bike with a particular set of tires on a particular track, Newton’s laws impose a theoretical limit on lap time. I don't know how close to that limit the best humans have come, but it wouldn't surprise me too much to find that it's within a second or two.
