Aside from the advertising angle, there's not many of those 'benefits' listed there which couldn't be achieved more cost effectively than with a traditional sticker (i.e. the handicap badge, etc). Police cars tend to already identify stolen or unregistered vehicles, and I don't see why adding vanity messages would be worth the additional money.
All I can see here is increased complexity and cost, with a much shorter lifespan than a traditional aluminium or plastic plate.<p>Of course, setting it up to have a refresh rate that was out-of-sync with multinova speed cameras (and distorting any captured image of it) would be interesting.
I always thought digital license plates would be privacy controls against ALPR. You could thwart casual trackers by displaying a rolling code that only police could link to a specific vehicle registration, ideally generating an audit trail along the way. Or skip plates entirely and do a cryptographic challenge/response with a transponder. Updating registration stickers is such a weird non-problem to solve. They could've done that server-side years ago.
Finally? So typical to embed the propaganda at the lowest level.<p>only took 3 years "finally!": <a href="https://news.ycombinator.com/item?id=8950403#8950625" rel="nofollow">https://news.ycombinator.com/item?id=8950403#8950625</a><p>Whew, glad that "finally" happened!<p>CA is like the England of the US. Collapsing under it's regulatory weight, but not fast enough.
