I added a few questions to that lesson this year. I feel best when there are a nice, round 10 questions.
Access the video here (I recommend downloading videos for classroom use):
Top Gear's Reliant Robin
Oh, and I did figure out how to post the video here for additional convenience. Isn't it nice to learn?
Updated question set and answer key:
Rolling through Roundabouts in a Reliant Robin
What do you do with a 20-minute class session? Let me know in the comments.
