No way it was intentional and as a fan, it was painful to watch. For whatever reason it failed...weather, microfractures, not actually toughglass...it should not have been demoed without confirming it could be done with a ball of larger size first. Safety factor.
It reminded me of Samsung software gimmicks. The sledgehammer swing was clearly babied compared to the F-150 door. Don't demo it if you can't showcase it truly.
The Google Soli demo's were less cringy, even though we all know it was under completely controlled conditions. At least it didn't break during the presentation.
