Lucas di Grassi won the Formula E championship this year. Besides having a ton of driving skill, he also holds a number of strong opinions, and can be very expressive in pronouncing them. One of my favorites quotes from him is "Sound is a waste of energy." It came during a unique interview. Basically, he was driven about in a classic 1965 Lotus Elan S3 Coupe and peppered with questions. It's a long interview, but it's broken into four parts. I'll link them all below.
