#HTE

Happy Pi Day! There are many circular sights to see from the Overview perspective, including the Nardò Ring — a high speed, 7.8-mile-long (12.5 km) test track in Nardò, Italy. Each of the ring’s four lanes has a determined “neutral speed” and is banked in such a manner that one can drive as if the road were straight. In fact, a driver in the outer most lane doesn’t need to turn the wheel while driving at speeds of up to 149 mph (240 km/h).
