Ibrahim Aycan has been waging all-out war against the electric minibuses newly introduced on the car-free island of Buyukada, which he says threaten his corner of paradise on the southern shores of Istanbul.
"We live a peaceful life here," said Aycan, a lawyer and head of the Association of Friends of the Island.
"These vehicles sadden us. Let people walk and cycle!"
Buyukada is one of the Princes' Islands, a popular destination for tourists and a retreat for many of Istanbul's 16 million inhabitants.
Motor vehicles are prohibited on the islands, except for essential services, and even horse-drawn carriages were banned in 2020 to protect the local wildlife.
But the controversial new minibuses, with a capacity of 12 people, went into service on June 15, driving through the narrow alleys of the islands.
As one of the protest leaders against the new mode of transport, Aycan uses his body as a roadblock whenever he comes across one of these "monstrobuses" -- a name given by islanders in Buyukada -- the largest of the Princes' Islands, in the Sea of Marmara.
"I saw a bus on the way to my home yesterday. I had an appointment but I froze in front of it for half an hour," Aycan said.
Eight protesters were detained on the first day, and locals have staged demos daily and spontaneously since.
Kamer Alyanakyan, 58, has spent every summer on Buyukada since his childhood, which is home to white wooden villas with gardens filled with colourful Bougainvillea plants.
"Nobody asked our opinion. The island's streets are pedestrian, and we don't want to lose that identity," said Alyanakyan.
He has been knocking on doors to persuade residents to sign a petition calling for the removal of the minibuses.
Mehmet Can, whose cafe is a 40-minute walk from the pier, admits the new buses could have been "smaller" but he says they are "more comfortable".
Above all, he sees them as "necessary in summer" because tens of thousands of people flock to the islands daily.
"(Authorities) will not throw them away just because a bunch of people are barking," he said.
Istanbul Municipality, run by the opposition CHP party, has defended the minibuses and said that public transport is "indispensable for the island's inhabitants", especially the elderly.
It also argued that these minibuses are accessible to people with disabilities, unlike the existing small electric shuttle service.
Istanbul's city council, a non-profit body that is in close dialogue with the municipality, has opposed minibuses.
"We support the islanders who want to defend their pedestrian streets," the council said.
In the 1930s, cars were banned on the islands and since 1984, it has been a pedestrian zone and a protected area.
Alyanakyan is convinced that the municipality will eventually back down.
The activist will join a festival in July on Mackinac Island near Detroit -- America's car capital -- which is known for its car-free roads.
"I'm going to talk to people, to the authorities over there," he said.
"I will ask them: 'How did you hold up? How did you resist the pressure?'"
