A local city proudly mentioned on the news that they had a system that could track TPMS sensors. Pretty much all cars after 2008 uses TPMS sensors that each broadcast a unique identifier to the car. They aren't hard to remove, and you can buy valve stems that fit your car (0.452 hole) at any auto parts store.
EDIT: The sheer amount of replies to this post days later that basically state "This is too hard to do, and it won't work anyway, so you are stupid to try and shouldn't do it", all from people who clearly have no real idea how the TPMS system on a car works, have confirmed for me that I was correct in spending a half hour removing these devices.
By "aren't hard to remove" you actually mean requires dismounting the tire from the rim, remounting it, and then balacing it. This is far beyond the capabilities not to mention equipment of the typical layperson. Plus, your state is likely to conveniently fail your car on its next inspection for a nonfunctioning TPMS system, same as your check engine light.
If you're going to go the distance anyway, get your tire shop to mount aftermarket Autel sensors in your rims. Using the readily available diagnostic tool, you can occasionally reprogram those (wirelessly!) with a set of random IDs and then also program your car to use them. You'll be a lot tougher to track if your signature is different every week.
I'm not about to do this just yet, but I do have the tool for more mundane purposes and I only paid around $200 for it several years ago.
It seems most states with mandatory vehicle inspections don't fail for TPMS problems.
https://www.tirerack.com/upgrade-garage/what-are-state-tpms-regulations
That only lists 18 states...
My own state requires it despite that list implying they don't. Thus I really don't think that chart is completely accurate. If you have ANY warning lights on your dash at inspection you will be failed here.
I did say most, not all. Some of the info on that page may be outdated, but obviously it would just be limited to those that require regular comprehensive inspections in the first place.
I was able to easily look up the inspection guidelines from my states DMV page and confirm for myself that TPMS light is not a fail here so YMMV, but my point was essentially that it's more likely than not that bad sensors won't fail someone, not that nobody will get failed.
18 out of 50 is not ‘most’.
There aren't 50 states with mandatory safety inspections, try educating yourself before making nonsense arguments.
k
Fool.
Well crap, that's not a cheap solution but I'm glad you commented because I didn't know these Autel sensors existed and that you could reprogram them. I mean, this threat is semi hypothetical right now (not like it's been used in the wild by authorities or anything) but one day it might be. Continual reprogramming would be a valid solution.
Your who is going to do what now?
(Posted from a state that doesn't check anything except emissions, and even then only for some cars in some urban areas.)
Fuck that sounds like a place full of dangerously badly maintained vehicles...
Surprisingly, most people aren't actually suicidally negligent in the absence of government regulation.
You would be extremely surprised. Car maintenance is expensive, and lack of inspection very often leads to people driving vehicles that should have been off the road years ago simply because a lot of states that axe it, axe inspections because they're expensive for the driver (a lot of these states are in the former Steel Belt). In better-off areas or places where people have more time/money/equipment/space to wrench on cars, then yes, but here in my city, I definitely have seen cars where the entire frame is basically being held together by Bondo and prayer, cars where they're running on 4 spares, cars where enormous sections of the body paneling are just gone. I've nearly been hit by people who clearly relied on yearly inspections to tell them "hey your brakes are failing" because they drive on autopilot and just adjust how they drive to accommodate failing/failed brakes.
In fact, I suspect maintenance costs are HIGHER in areas without inspection, because shops could rely on that regular-ish influx of cash even if it was only like $50-$100 a vehicle, AND you have the customer in the shop, so it's easier to go "hey you really need brakes, it'll cost you an extra $200 and take an extra hour or two".
+1000, but you still see it in places with plenty of money and space to work on cars.
I worked at a car repair shop when I was younger. I agree that it's not most (as in > 50%) but the number of people who knowingly drive very unsafe vehicles is bigger than you'd think.
That is actually surprising, given people.
State inspections are a racket. This is coming from a state inspector. Waste of time and money! I only got certified so I can inspect my own and wife's vehicles. Well that and it's invaluable at work but shit if your determined to drive an unroadworthy POS the lack of a sticker on ur windshield and the possibility u MIGHT get a 50$ fine and no points is not enough to deter the idiots from driving rolling scrap heaps anyways. Seen em before and will continue to see em weather inspections are mandated or not.
Yeah, a couple problems with that:
As always, these are systems of convenience, and the alternative is to check your tire pressures every day before leaving home.
Older cars use a wheel speed sensor-based TPMS. It's not as effective or reliable but it also doesn't emit any signals that can be read by other devices.
I managed to drive cars for 30 years without a TPMS sensor and the only time I ever had a to check the pressure on a tire, was when I knew i had a leak and didn't have time to fix it. I can also tell by the way my car drives if a tire is soft. I also had an air pump in my car powered by a cigarette lighter adapter that I could fill my tires.
My current car, from 2019 doesn't have one. I've managed to own it 7 years (this week) without needing to check the pressure 2500 times.
The assertion you need to check your pressure everyday without a TPMS system is ridiculous.
not why they were mandated.
The US and Canada at one point could hit their Paris Accord C02 ouputs just by keeping car tires properly inflated.
They aren’t hard to remove, and you can buy valve stems that fit your hole at any auto parts store.
Good to know.
They are hard to remove, and require a variety of expensive specialty tools to do properly.
