Everywhere in the world you design for what the local conditions are. I bet Mumbai doesn't mandate winter tyres in winter, right? Sweden does. If suddenly one winter you see -10℃ in Mumbai, would you appreciate Swedes mocking you for not being able to drive in a car not designed for it, with tyres not designed for it, on roads not designed for it, etc…? Nothing in the UK is designed for 40℃. Buildings, the type of steel made for train tracks, ventilation in tube tunnels, the asphalt, the walls in the building, the windows (no double glazing in Mumbai, I assume?). I would expect everything in Mumbai is designed to handle high temperatures. But not cold.
