Once again an intrusive government regulation that will accomplish next to nothing.

Why?

Because not every Californian is as stupid as the dumb greens and Bureaucrats think. They ALREADY have sun filters and window glazes on their cars. A random check of the cars in any California parking lot will find that it is almost impossible to find a car WITHOUT the glazes and window tinting films there already.

Much ado about nothing. Merely more justification for now useless bureaucrats to keep their sinecures.

Let's remove all regulations and go back to coal burning home furnaces, open sewages, open garbage dumps, open wood fire places, steam locomotives, farm horses, whale oil lamps, unpaved roads, and close all those expensive public schools, hospitals, library, arenas, vaccination centers, filtered clean water plants, public roads, and all churches and charity organisations while at it. It may help to solve the world ever growing population in less than one century?

If the world was to listen to objectors and those in constant denial, we could be driven back 1000 years with revival of major plagues etc.It would certainly be another world.

This is the danger of building these large government infrastructures. They need to find stuff to do. Why not make this a dealer option alone and let the car owner decide if they want to spend less energy dollars on air conditioning? Or buy a $10 mylar windshield reflector at Pep Boys to accomplish the same thing.

That would mean less bureaucrats.

Come on. It would be so easy to use a roof top exterior antenna for GPS + Cell Phones + Radio + TV etc. It would even improve the signal in most cases.

Holding a cell phone in your hand (and potentially using it) while driving is against the law in our area. The penalty is $300. Evidence with/from the new road side camera stations used to catch speeders and bad drivers is enough. No on-site policing is required.

Hands free systems and 10% over the speed limits are allowed.

Censorship of data, manipulating data, hiding data - is the first love of fascists. Fascists find it far easier to use trickery and manipulation to get their way - than to educate people on legitimate issues. They are basically lazy bureaucrats without any understanding of human nature. It is entertaining to watch them crash and burn.

reel$$,
The dealer and buyer will be equally pissed at changing the windscreen for the other one and there is no financial benefit , only cost to do so.
The $10 screen will kill the fuel economy and probably breaks the regulatory laws in doing so. It certainly wont be cost effective over the life of the vehicle.

It's good to see your loyalty and faith in the usual suspects is so misplaced.

I can explain how making windows block cell phone signals MIGHT work: Presently these reflective windows block (or attenuate) GPS but not cellular transmissions - without tuned circuits.

This may be mostly due to the signal/noise ratio but I believe also due to the frequency range.

Trees (lack of line-of-sight) easily blocked the GPS signal to older GPS receivers (newer receivers are much better) but never affected analog or digital cell phones.

I suppose the metallization could be patterned to form a reflective surface for cell phone frequencies but I believe the attenuation required is too high.

Or the cell phone companies would be required to transmit a enable signal that would be blocked in a car.

BUT - as ai_vin succinctly points out “the only thing more dangerous than a nitwit talking on a cell-phone while driving is a nitwit driving while trying to figure out why his cell-phone isn't working.” [Or while trying to defeat the blockage.]

AND - I also said that it was probably unworkable.

Aha, I think I understand.

My conclusion is (like most others) that we do not need a law requiring window tinting.

A little off the subject, maybe require all cars to include a device that disables 2 way cell phone communication but lets both sides know why.

If you think your message is important ("come back, you jerk, you forgot your wallet - and your pants") the caller could "redial" 2 or 3 times and the nitwit who would otherwise be talking on a cell-phone while driving, is forced to pull over and get out; away from his car.

Not so good, and more laws are to be resisted, but maybe better than with dangerous, preoccupied nitwits driving while talking or (lord help us) texting.

And we would readjust to this inconvenience – and learn to watch out for those zombies on cell phones stumbling around by the side of the road.

Tom,
You are a good 'sport' and dont take a criticism to heart, that's good.

In my writing here, there is a creative license for metaphor, fantasy, vis concepts, and real life experience. I.E. I will refer to the 'kids' when the post gets a little 'out there' as kids can get away with anything. I might be referring to myself, someone else etc.

There are generally so many Laws AND Regulations
that it can be hard to function on a daily basis.

I differentiate between interference and protection to evaluate the article.

There are very many (often understrength) laws that protect us all on a daily basis. These could be unhelpful to those who could say make more money if that law did not exist.

In a life threatening situation, no one will pay too much attention to the applicable law or regulation and that is understandable. I.E. A starving person will be understood helped and rarely punished in many countries if they steal bread (these days) unlike those transported to the colonial territories 2 centuries ago.
There are even cases of cannibalism and necrophilia where rescuers look the other way in the understanding of a higher priority.

The best well known example IMO of a 'Dysfunctional' law designed to minimise harm to society esp the youth, are the drug criminalisation laws.

IMO these laws enable high profits, corruption and incentivise the rebellious 'red belt' nature of teenagers making it an attractive challenge. The cost to society become overwhelming and we end up in the state driven mess that IMO would be easily resolved with an educative approach. 'Kids and others aren't stupid'

There are many contributers to this site who object to regulation on the basis that 'it is'.
They may object to criteria pollution laws that cause higher fuel consumption, cafe type laws that either reduce (or enable) fuel consumption and have mitigation costs.

There are many Regulations that are benign. this reflective glazing air conditioning load reduction Regulation eets my definition of a benign and useful Regulation.

If I had a bunch of front screens sitting in the parts shed (I wish) you can be sure that with a similar climate to Ca, the ones I would place the highest value on as the most desirable will be the very reflective one that reduces air con loads (maybe a broken or undergassed unit doesn't use much fuel anyways) whilst making the driving experience more pleasant and saves money by reducing fuel consumption.

Evidence based analysis will show many laws that really dont work and need repealing. But I understand the 'republican' 'freedom to pursue anything' capitalist doctrine perpetuates itself via dogma. This mentlity suggests that no law can ever be good when it inhibits the opportunity to make money.

This leads to the no tax no carbon tax, no CO2 "issue"
dogma that becomes mindless and unrelenting with the proponents lost in self harming objectionism.

The "holy cows" like drug laws are sacred and the rationale (or irrational) adherence is lost in the religious mantra similar to cultural discrimination.

Other peoples caught in this 'human nature' category include ethnicity, sexual orientation, class distinction, people with disability including mental illness. In fact nearly everyone is catered for when you think about it.

Sounds like a Fascist State?

So for suleny's benefit, the hopeless bureaucrats have plenty they could be doing and there are many citizens that wait patiently for stronger protection. It' not the wild west but if it was, there wouldn't be any overpopulation issue and we could all have it pretty much as we want it.

There you have it.
