Yeah, but us humans have been improving top level competition laptimes by tenths or hundredths of seconds a year at best. How quickly do you suppose the machines are going to improve over a few years or decades?

(Last night's fastest lap in the MotoGP race at Mugello was 5 hundredths slower than the class lap record set back in 2013. Admittedly there've been rule changes, but the humans aren't getting much faster.))
