IP cameras, IP speakers, IP toasters... IP license plates?
The next generation of license plates is making mainstream news, being called 'digital' and 'smart'. One thing they certainly are is networked as these license plates will be connected to the cloud for remote update and management.
One large potential security benefit is being able to know and report the real-time positioning of cars. This could be then used for responding to emergencies or more broadly tracking suspects or wanted individuals.
Or selling the data to repo agencies. Or tracking someone down over an unpaid parking ticket, past-due water bill, or who knows what else.
I didn't love the OnStar system in my GM vehicle, due to the ability for misuse, but was kind of OK with it because it was the vehicle manufacturer, not a government agency. Not a fan of installing any kind of device with live-tracking capabilities that is administered by fed/state/local governments.
Strap a $700 tablet on one of the most vulnerable spots of your car. What could possibly go wrong? I don't think people realize how many times your car gets bumped/tapped/scraped in parking lots and in every day life.
Among other things I work closely with LPR systems in my current job and seems everything the IP license plate purports to offer LPR can essentially already do - stolens, uninsureds, vehicle description, etc - all without the unnecessary steps of the IP solution, including the potential damage it could easily incur.
Nifty idea on the surface until you drill down into the practical layers. That said, I am never one to trash any novel ideas. Keep them coming, that's how we progress.
Over burden cellular systems in traffic jamb events Battery drain on parked vehicles Use a lot of tablet raw materials, rare earths run out quicker Will attract more roadkill bugs & critters Unreadable in bright sunlight Very likely deficient on older vehicles - those more likely to be queried Software 'updates' crashing the entire fleet Bright/dark pixels reducing clarity Trashed by lightening/flooding/rain/hail/high temperatures/ice/stones/fire Useless just after an accident, when they are most needed EMF pollution (like smart meters) Unsuited to junk yard 'collectors'
They seem to be against every design principle of 'real' licence plates
On environmental damage, there are merits in avoiding such electronic gadgets.
While 5G will take care of the cellular coverage, it may be better idea to add some intelligence in the car itself or the number plate by adding some chip. This may provide location (current and history), vehicle ownership, speed etc in much efficient way than how we get it today.
I agree with your design principle critique, and most of your points but I do have some contrasting thoughts as well, mostly related to the plate displays being e-ink screens. They will have very low battery drain, low EMF pollution (albeit more than a standard plate), should be readable in bright sunlight, and shouldn't attract more roadkill bugs/critters than a standard plate.
Since it will likely cost the government and not the vehicle owner directly, watch for mass vandalism events where hundreds of these stupid things are smashed repeatedly. That bill will add up VERY fast.
