In 2011, Philadelphia native Patrice Banks had been working as an engineer for 10 years when she realized that while she may be an expert at diagnosing what was wrong with the equipment in her company’s lab, when it came to what was under the hood of her car she was completely lost.
So Banks posted an informal Facebook poll, asking her female friends to name their No. 1 knowledge gap. They overwhelmingly returned the same answer: car maintenance. “That was my ‘aha!’ moment.”
