LAS VEGAS (AP) — It’s been 40 years since Formula One last ventured into Sin City for back-to-back Las Vegas races staged in the parking lot of the Caesars Palace hotel. The European-headquartered series raced in Las Vegas in 1981 and 1982, then packed up with little incentive to return. Then came new ownership, slick marketing, a Netflix docuseries and a historic championship battle that all helped F1 explode in popularity throughout the United States. Now the U.S. will be the only country on the 2023 calendar to host three F1 races in one season following Wednesday’s announcement of a Saturday night race down the famed Las Vegas Strip.
