Sometimes the future trips over something entirely simple - a door handle. The US road safety regulator (NHTSA) announced it will consider new rules that would require all car manufacturers to guarantee that passengers can safely get out of the vehicle. The trigger is a series of accidents, some of them fatal, in which people were left trapped in cars with flush, electronic handles - exactly the kind that Tesla's vehicles carry.

The decision came in response to a request to open an investigation into the design of the emergency mechanical opening on the 2022 Tesla Model 3. The regulator declined to open the investigation as the petitioners had asked, but said the problem is better solved through new rules than through an investigation into a specific defect. If such rules really are adopted, they will apply to all manufacturers, not just Tesla.

The problem is concrete and terrifyingly simple. Tesla's vehicles do have a manual opening, but only from the inside. In an initial inspection, inspectors found that the electronic handles may not work if the locks don't get enough voltage from the vehicle's battery. Translated: if the power fails after a crash, the door meant to save you can stay locked. Less than a year before this, the regulator had already opened an investigation after receiving nine complaints from owners who couldn't get into their cars - sometimes with children locked inside.

The industry quietly admits it knows. Tesla's designer, Franz von Holzhausen, said last year the company is working on a redesign of the handles. Rivian, for its part, announced it is changing the interior handle on its R2 model, so the manual opening is in a more visible place. So the problem isn't a secret even to the firms themselves - simply, a design that looks futuristic and sleek was more important than a design that opens the door when the power goes out.

And here is the lesson that reaches beyond a single car brand. For years the industry sold flush handles as a symbol of modernity - no handles, no buttons, everything by touch. And now it turns out that something humanity solved a century ago, the plain mechanical handle every child knows how to pull, is back as a matter of life and death. How many times will technology have to “reinvent” the safety we already had?
