A Bengaluru entrepreneur, Siddharth Dialani, runs a public experiment to test whether strangers will take responsibility for personal safety items in the city. He and his wife leave their helmets unlocked on their two-wheeler each time they go out, using the setup as an informal test of whether the helmets remain untouched.

According to reports, the effort has been ongoing for about five years and has drawn attention online after the results of the practice went viral. NDTV describes the experiment’s basic method—leaving helmets in the open rather than locked—to gauge how people behave when items are left unattended.

While outlets focus on the viral angle and what it suggests about day-to-day trust and accountability, the core details reported are the same: the helmets are left unlocked and unguarded during outings as part of a longer-running experiment in Bengaluru.
