I love Car Talk - the nerd humor, the constant laughter, etc., but the gender stereotype humor gets old. In this show you told Emily that her male friend's reaction of shame and embarassment when she helped him diagnose his car should be treated as a learning experience, which I assume means that she should play dumb next time and pretend to know nothing about cars so she won't bruise the guy's ego. I hope that Emily doesn't alter the way she acts in the future at all. She should be proud of her knowledge and she should find friends who won't get weird about the fact that she is intelligent and interested in mechanical things. I try very hard to encourage my tween/teen daughters to be interested in technical things - coding, physics, mechanics, etc. It is this kind of "guys will be guys" attitude makes it so difficult for women to feel comfortable working in STEM fields. Maybe tell the next "Emily" that it's great that she knows something about cars and the guy should have apologized for thinking her idea was wrong and thanked her for helping.
