This present edition of our “Human Engineering” article features a man who is not actually an engineer, although we believe the exception, in this case, is worth making.
“I am a licensed commercial airplane pilot with two undergraduate science degrees and two master’s degrees,” said James Joseph “JJ” Miller. “At NASA, I am a technologist manager overseeing the work of a team of engineers at several NASA field centers across the USA.”

There are a number of challenges to localization of autonomous vehicles (AVs) and autonomous driving (AD) applications in northern latitudes. The primary challenge is the harsh winter weather, which limits the utility of imaging sensors — snow, fog, mist, and darkness adversely affect such sensors and extreme low temperature can affect sensor performance. Ice and snow on the roads magnifies slippage of wheels, reducing the accuracy of wheel-mounted sensors.
