Five years, zero stolen helmets: Bengaluru couple’s unusual trust test goes viral

BENGALURU: What happens when you leave your helmet unlocked on your parked two-wheeler in Bengaluru and simply walk away? For entrepreneur Siddharth Dialani and his wife, the answer, so far, has been surprisingly simple: nothing.

The couple say they have been running an unusual social experiment for the past five years, leaving their helmets unsecured whenever they park their two-wheeler. Instead of locking them away, they leave the helmets on the side mirror or the seat and head off. And after five years, Dialani says, not a single one of their helmets has been stolen.

Dialani, an IIT Madras graduate and founder and CEO of BharatAgri, shared the experiment on X, saying the idea was to find out whether Bengaluru could be considered a “high-trust city”.
The post quickly went viral, prompting a bigger question: does the untouched helmet say something about Bengaluru — or is a helmet simply not tempting enough for a thief?
The reactions were sharply divided.

Some users said Bengaluru residents routinely help strangers and show concern for people they do not know. One commenter suggested that relatively smaller differences in income and living standards could mean there was less incentive for people to steal.

Dialani did not agree.
He argued that Bengaluru actually has significant income disparity, but people still have the self-respect not to take someone else's belongings.

Others, however, were quick to challenge the experiment with their own experiences. Several users said they had lost helmets while living in or visiting Bengaluru.

Then came another explanation: perhaps the experiment has less to do with trust and more to do with the value of the item.

Some commenters pointed out that helmets are not necessarily valuable enough to attract thieves, suggesting that a similar experiment with a more expensive helmet might produce a very different result. Others argued that people in other cities might also leave an unlocked helmet untouched.

So, does five years without a stolen helmet prove Bengaluru is a city of unusually trustworthy people?
Probably not.

It does, however, make for one unusually effective test of the city's reputation — and a surprisingly lively internet debate.
Dialani's experiment also comes with a simple end point: if someone eventually walks away with one of their helmets, the couple plan to stop parking in that particular locality.
For now, though, the helmets remain where they were left — unlocked and apparently unwanted.
