Last week, a ruling Democratic Progressive Party (DPP) legislatorLin Chu-yin (林楚茵) made headlines by claiming to have exclusively revealed that electric buses in the Taipei metropolitan area were equipped with Chinese-made chips — and might therefore be functioning as "spy buses."
The allegation sounds alarming. But the most alarming thing about it is not the supposed security threat. It is the combination of ignorance and populism that produced the claim in the first place.
The legislator, Lin Chu-yin, raised the issue during a legislative interpellation session. She targeted two bus companies — Hsin Hsin and Danan — affiliated with the Veterans Affairs Council, a government agency overseeing welfare and business operations for retired military personnel.
Her allegation: the panoramic camera systems on their electric buses used Chinese-manufactured chips, potentially creating national security risks. The Veterans Affairs Council responded by pledging to replace the components and pursue breach-of-contract claims against the supplier, a company called Chuang Yi.
Both the legislative questioning and subsequent media coverage treated this as gravely serious — evidence, it was suggested, of Beijing's relentless technological infiltration reaching into the daily commutes of ordinary Taiwanese citizens.
What could a bus chip actually collect?
Anyone with even a basic grasp of how technology works should recognize this framing for what it is: sensationalism built on ignorance.
Start with the most fundamental question: what exactly could a chip embedded in a city bus realistically collect? Even granting it some hypothetical intelligence-gathering capability and the ability to transmit data across the strait, what would it actually capture?
These vehicles run fixed routes through Taipei and New Taipei. What sensitive intelligence is available on a bus route? Street-level imagery? Google Maps and Street View already provide comprehensive visual coverage of Taiwan's cities, freely accessible to anyone.
The "spy bus" framing collapses under the lightest scrutiny.
Not even by Beijing's own standard
A more instructive comparison comes from China itself. Beginning in 2021, Beijing restricted Tesla vehicles from entering military bases and sensitive state enterprise facilities — citing national security concerns.
That restriction at least had a coherent technical rationale. Tesla's Sentry Mode continuously records visual data from cameras around the vehicle, and all data is transmitted back to company servers to improve its autonomous driving systems. There was a genuine, identifiable pathway for data collection and transmission.
Even so, China's restriction applied only to sensitive facilities — not to ordinary city streets. The "spy bus" logic does not even clear the bar set by Beijing's own cautious approach.
If buses, then what about smartphones?
If Chinese chips in 82 buses constitute a national security emergency, the same logic demands urgent action on far larger and more obvious cases — of which there are many.
Consider smartphones. How many Chinese-manufactured handsets are carried daily into every corner of Taiwan — including sensitive government buildings, military facilities, and private residences? Apple iPhones, assembled in China and accounting for roughly half the Taiwanese market, contain components sourced and manufactured there.
Other brands with even more direct Chinese origins — OPPO, Vivo, and Xiaomi — collectively rank among the top five handset brands in Taiwan. Vivo, notably, designs its own image-processing chips in-house.
If Chinese chips in buses are cause for alarm, why are Chinese chips in smartphones, carried by millions into every conceivable location, not treated as a far graver threat?
And what about Tesla
Then there is Tesla. It is an American brand, and its high-end chips — including the full self-driving processor and core vehicle computer — are American-designed and manufactured by TSMC and Samsung.
But a modern electric vehicle contains vastly more chips than those headline components. Many of the mature-node chips handling secondary functions in Tesla vehicles are manufactured in China, some even designed there. Tens of thousands of Teslas travel Taiwan's roads daily. By the internal logic of the "spy bus" argument, that surely warrants greater concern than 82 municipal buses.
Extend the inquiry further and the problem becomes unmanageable. Panoramic camera systems — the same technology at the center of this controversy — are standard across numerous vehicle models sold in Taiwan, including top-selling Japanese brands. Many also use Chinese chips. Are those vehicles security threats too?
The arithmetic makes the premise untenable
The arithmetic of modern automotive manufacturing makes the entire premise untenable. A contemporary electric vehicle contains between 1,500 and 3,000 chips. Even a conventional combustion engine vehicle requires 500 to 700.
The vast majority operate on mature process nodes — defined as 28 nanometers and above. China's share of global mature-node chip production already exceeds 30 percent, is projected to reach 40 percent next year, and is expected to surpass 50 percent within three to five years.
A report by Japan's Kyodo News earlier this year cited data suggesting that as of late 2024 and early 2025, approximately 70 percent of global mature-node chip orders were flowing to Chinese manufacturers.
Taken to its logical conclusion, the legislator's framework would eventually leave Taiwan with no vehicles it could legally put on the road.
The real issue: a contract violation
None of this means the situation with these 82 buses should be ignored. There is a legitimate issue here — but it has nothing to do with national security.
According to the Veterans Affairs Council's own account, the relevant procurement contracts explicitly prohibited the use of Chinese-manufactured components. The supplier appears to have violated those terms.
That is a contractual and procurement compliance matter, and it should be handled as one. Dressing it up as a national security crisis does not make Taiwan safer. It makes public discourse less serious.
