Deepfakes are about impersonating the person in the video, fake news is… Well, just someone lying. Signatures are meant to verify the source of information, not the contents of it.

Simple example, we can be nearly 100% confident that the person posting tweets under the Trump account is (atleast authorized by) Trump. Doesnt stop him from lying nor uploading a deepfake video.

Hard disagree on this one. The regenerative braking has a learning curve yes, but the pros outweigh the cons imo. When you brake (in a traditional car or an EV), you are wearing out yor brake pads, turning friction into heat. Done right, renerative braking means almost all energy is captured back, and even lower maintenance by not bothering the brake pad.

It takes getting used to, you hate it at first, which is why tesla has an option to disable it, but there is a reason why most people who own Teslas use it, and other EVs are getting it as well.
