Did you know that a modern Formula 1 racecar could theoretically drive upside down in a tunnel?
A recent MIT study showed that these vehicles produce 3.5g of force when taking corners. This combined with their front and rear wings would hypothetically create enough aerodynamic downforce to drive the vehicle inverted at speeds over 240km/hr.
Unless you are a Formula 1 driver with a physics degree, we do not recommend trying this yourself!
