This opinion piece warns New York against adopting a 15 mph speed limit in school zones, drawing parallels between New York City official Zohran Mamdani and London Mayor Sadiq Khan. The author, a Londoner, argues that London’s 20 mph limit has “disastrous” consequences, making the city “ground to a halt” and drivers “cash cows.” The article claims that similar “Stalinist car-phobic madness” from Khan has led to increased crime, “eco-quackery,” and “toxic identity politics” in London. The author fears Mamdani will inflict the same “lunacy” on NYC, criticizing congestion pricing, Net Zero initiatives, and alleged “Israelophobia” as detrimental policies that “immiserate Joe Motorist.”
