On December 20, 49ers wide-receiver Brandon Aiyuk posted a YouTube video in which he test-drives a Cadillac CT5-V Blackwing. A speedometer reading of “104” sparked a viral debate over whether the unit was in miles or kilometers per hour.
Video Controversy
If the figure represents miles per hour, Aiyuk was well above the 40-mph limit on Tasman Drive near Levi’s Stadium. If it is kilometers per hour, the speed equates to roughly 64 mph, still exceeding the posted limit. The clip shows Aiyuk traveling faster than the speed limit, prompting the player to issue an apology on his YouTube community page.

Player Response
Aiyuk issued a public apology on his YouTube community page after the video went viral. Neither the 49ers organization nor the NFL has addressed the incident.
Police Review
The Santa Clara Police Department has acknowledged the video and is reviewing it. A spokesperson told TMZ: “At this point, the video is being reviewed, and further details can be provided when available.”
