Tesla’s over-the-air brake upgrade was amazing—and also a bit worrying
Tesla pushed out a software update to Model 3s that dramatically improved the car's braking performance in certain conditions. The update came days after Consumer Reports announced that it could not recommend the vehicle based on inconsistent—and sometimes quite poor—braking performance.
This week, after the update had gone out, Consumer reports tested its car again and found the braking had improved. As a result, the organization is now recommending the Model 3.
The update shows the power of Tesla's over-the-air software update capabilities. But it also raises questions about how much testing Tesla did to its braking systems before launching the Model 3 in the first place.
