To be fair, they both agreed to make the whole bet public. They went on video, with "science celebrities" like Neil Degrasse Tyson and Bill Nye, and I believe they even signed something? It's kinda hard to backup from that. It also was a UCLA professor, so not quite some random person on Twitter. EDIT: As an aside, I would also add that the original video did a poor job at explaining, and the demo had clear flaws which were the points the physics professor was making. More specifically, his 2 main points were 1. It's possible that when the picture of the flag was taken, the wind was slower than the car, but the car was still moving faster due to momentum 2. It's possible that the wind speed up at the propeller level is different from the ground level where the flag was Those were both very valid criticisms, even though they didn't actually matter in the grander scheme of things.
