Dirty Air Bad; Slipstream Good (Patreon)

I still get asked about this a LOT and have wished for ages I didn't have a very low quality, pretty naff powerpoint video to point to. So I thought about how to talk about the idea a bit harder and made a revamped video on the topic. 

Also been playing in After Effects and updated my 'aero lines' effects. Even though it takes much longer to render!

Now... what to do for the next video?
