The Lidar Paradox: National Security vs. Cost Competitiveness

The US government’s review of Chinese lidar sensors has sparked a long-overdue conversation about the risks and benefits of using foreign-made technology in critical infrastructure like autonomous vehicles. This issue is complex, with trade-offs between national security concerns and cost competitiveness.

Using Chinese lidar sensors could pose significant risks to American communities and national security if they contain “back doors” that allow data to be transmitted back to Chinese interests. Senator Tammy Baldwin’s bill, aimed at banning the use of Chinese lidar, highlights these concerns. It is difficult to argue against her assertion that taxpayer dollars should not be spent on technologies that might aid espionage.

However, the cost of lidar has plummeted in recent years, making it an attractive option for companies looking to reduce expenses and stay competitive in the rapidly evolving autonomous vehicle market. American lidar makers have struggled to keep pace with Chinese companies like Hesai and RoboSense, which have leveraged economies of scale and lower labor costs to drive prices down.

This raises questions about the long-term sustainability of an all-American approach to lidar development. China’s government has deemed lidar a strategically important technology, and if US companies are unable to compete on cost, they risk being priced out of the market altogether.

The Idaho National Laboratory review is focused on cybersecurity risks, but it remains unclear whether this will give Chinese-made lidar a clean bill of health in this area. Even if individual sensors can be disabled or their data extracted, there are still significant security concerns surrounding the widespread use of Chinese lidar.

A potential consequence of relying too heavily on foreign-made lidar is the creation of a single-point failure in our critical infrastructure. China’s government has already demonstrated its willingness to use technology as a tool for espionage and coercion – what happens if we’re forced to rely on Chinese companies for a crucial component like lidar?

Some companies are exploring joint ventures or shared alignment with lidar firms to develop production capacity in the US. This might address some of the supply chain concerns, but it’s unclear whether this will be enough to mitigate the risks associated with using Chinese-made technology.

In an industry where margins are already razor-thin, the choice between cost competitiveness and national security is a difficult one. Automakers like Rivian are caught in the middle – they need to balance the financial realities of development with the desire to prioritize American-made technology.

However, as we move forward, it’s essential that policymakers consider the broader implications of this decision. Will we prioritize short-term gains and risk long-term security vulnerabilities, or will we invest in American lidar makers and ensure our critical infrastructure is not beholden to foreign interests?

The US government’s review of Chinese lidar sensors should be seen as an opportunity to re-examine our national priorities. We can no longer afford to treat cost competitiveness as the sole metric for evaluating technology adoption – we must balance this with a commitment to national security and the long-term sustainability of American industries.

To support American lidar makers in their efforts to develop competitive technologies, targeted investments in research and development may be necessary. Additionally, incentives for companies to prioritize domestic production could help ensure that our critical infrastructure is not compromised by foreign interests.
