> An IndyCar is heavier than a Formula 1 car: while a Formula 1 car weighs 1759 pounds / 798 kg including the driver, an IndyCar weighs 1700 pounds / 771 kg on road and street courses, excluding the driver.
The statement implies an assumption that the drivers weigh / mass more than 59 lbs. / 27 kg, as they are included in the first measurement, but not the second. This is a reasonable assumption, as even Indycar drivers are all adult males, and none are small enough to weigh / mass less than that.
This seems to contradict itself.
