Is this video talking about a different California bill? I can't find any resemblance between what the video says about the bill, and what the bill says.
The video says that the bill will add a 6 to 9 cent per mile tax and require realtime tracking of vehicles.
The bill text says it extends the expiration date of a committee looking into a mileage tax. That's all it does.
I'm not supporting what California is doing, just saying that this video is close to 100% fiction in what it says about AB 1421. Read it yourself and explain how the video is correct.
