If they know they'redoing it wrong then why put it on YouTube?Nowhere was it stated that it was a complete scientific test, and I assumed whoever watched the video recognize that it's completely non-scientific. Maybe it is true that nothing is too obviously nowadays.
It at least shows that there was no noticeable difference in those, hmm, driving conditions. I'll await your full scientific test results.
I'm not going to test it. I dont have the equipment or two similar cars of different builds. I think it's better to not do it than do it wrong
