For EV Safety Tests, AI Is Here to Help

It’s important to note that skepticism toward AI is reminiscent of past attitudes toward now-standard technologies. Thirty years ago, tools such as CFD were met with trepidation — an attitude defined by limited understanding. Today, engineers see them as indispensable. Similarly, adopting AI requires a shift in perspective and embracing its potential.

How Much Do You Know About Unattended Testing?

If we can remove clear indications that someone is being monitored, we are far more likely to get the information we seek. This is the basis for unattended testing, which is about as common as laboratory testing itself. So, how much do you know about unattended testing? Find out with this quiz.
