They made that claim because the videos are usually linked and viewed at low resolutions where it is hard to make out the specific warning message being displayed. As such, the Tesla promoters believed they could make up false claims that suit their narrative with no way for anybody to disprove them. Unfortunately for them, the raw footage is frequently made available in 4k resolution allowing video evidence to disprove their claims of a "warning message".
In no situation where they make claims that there is a "accelerator pressed" message is the imagined message adequately visible to clearly demonstrate their claim to be true. In contrast, every situation where there is a high resolution video the message is in the category I stated and they still make demonstrably false claims that the message is "accelerator pressed". Even in situations where the video is only low resolution, there is still frequently adequate display and color resolution to see that the shape of the message is more similar to a two-word "Supercharging unavailable" than a 5-word "Cruise control will not brake" or a center screen "Autopilot will not brake".
Seriously, I dare you to present a video clearly demonstrating the claimed "accelerator pressed" message rather than shaky-cam Bigfoot-level video used as "proof". I already presented clear video evidence of my claims.
