I drove 1800 miles in a Hydrogen Car

Kudos to the auto industry (all those participating in H-fuel cell adaptation). 
Also, well done D for your channel on delivering to us easy-to-understand scientific break-throughs.
However, we, who watched the video hungry for some science, are pretty disappointed when at 4:20 you allowed Toyota to fudge through the science in a condescending manner. Did they not only ban you from filming freely but also redact your material?
