Hamby drove 19,199.8 miles or 30,899.1 kilometres in his NASCAR Winston Cup Series career.
[citation needed] He formally competed in 18,446 laps of NASCAR racing, earning a lifetime total of $118,823.
[clarification needed][4] One of his vehicles was involved in a major crash in the 1979 Gabriel 400 when Steve Pfeiffer (replacing Hamby during the race in the No.
17 Chevrolet Impala) injured some spectators after a routine green flag pit stop went awry.
[5] As Hamby started the vehicle and made the substitution during the middle of the race, he got credit for the finish, not Pfeiffer.
