Rome's golf cart tour industry went from novelty to nuisance in roughly three years, and authorities are only now catching up. Police checks this week found that approximately 90% of the estimated 500 golf carts operating in central Rome lack proper authorisation — a staggering compliance failure that says more about the city's regulatory apparatus than about the carts themselves. Fines totalling €38,000 were issued after 131 carts were stopped near the Pantheon, Piazza Navona, Circo Massimo and the Spanish Steps. The demand side is straightforward. Tourists like Barry and Linda from Texas pay €100 to €400+ per person for tours lasting up to half a day. Their three-hour ride cost €310. Rome's cobblestones, absent sidewalks, and suffocating crowds make walking genuinely painful, and the golf carts offer a seated, breezy alternative. For visitors with disabilities or young children, the value proposition is real. The supply side is where extraction lives. An unregulated market means operators face near-zero barriers to entry — no licensing costs, no insurance overhead, no safety inspections. The margins on a €310 three-hour ride with minimal operating costs are enormous. Legitimate operators like Leo Pavoncello in the Jewish Ghetto complain that unlicensed competitors undercut the market while giving the entire trade a bad name. The 90% non-compliance rate suggests legitimacy is the exception, not the rule. Taxi drivers have been the loudest opposition, accusing golf cart operators of stealing fares. This is a classic incumbent-vs-entrant fight dressed up as a safety concern. Pavoncello suspects "taxi lobbies" are driving the crackdown. He's probably not wrong, but that doesn't make the regulatory vacuum acceptable. A city where 450 of 500 commercial vehicles operate without authorisation has a governance problem, not just a competition problem. Residents bear the externalities. Elisa Isacco in Monti describes dodging carts constantly in streets already choked with cars, scooters, Vespas, Fiat 500s, tuk-tuks, and the occasional horse-drawn carriage. Rome's street grid was built for foot traffic and the odd chariot — Julius Caesar banned daytime commercial vehicles two millennia ago for the same congestion reasons. The golf carts are simply the latest entrant in a zero-sum competition for finite public space. Eugenio Patanè, Rome's councillor for mobility, wants regionwide regulation before things "spiral out of control." The problem is that the spiral already happened. Regulating after 500 vehicles are already on the streets is enforcement, not planning. Any licensing regime will face fierce resistance from operators who've built businesses on the regulatory vacuum, and from tourists who've come to expect the service. The twenty-year question is whether Rome can build a transport governance framework that allocates scarce street space efficiently — or whether each new mode of tourist transport will follow the same cycle: emerge, proliferate, generate complaints, trigger a crackdown, and then get grandfathered in while the next mode starts the cycle again. The golf carts are a symptom. The disease is a city that cannot regulate its own streets.
