> cars have become more complicated and require more diagnostic equipment

For the consumable stuff every car owner has to deal with, nothing has really changed in 40 years, honestly! A brake service is still done the exact same way, same with virtually all the fluid services.

I just find far more people parrot "modern cars are so complicated" today and don't even consider that in fact, it is relatively simple to change a brake pad and disc, or your own oil, perhaps an air filter, even on most brand new cars. Fluids filters and brakes are like 90% of most people's maintenance needs nowadays.

YouTube has also massively lowered the barrier to working on cars, given there are multiple easy to follow guides for just about any car service for any car model you can think of.

Except many new cars are locked down in software, for example not allowing to release rear parking brakes without authorized service subscription, keeping the electronic keys for each VIN unique and stored in the cloud. Yes, there are workarounds on releasing the brakes manually but it is a burden.

Also similarly as with iPhones, many cars require connecting to the authorized service to change headlights and other parts since they are paired with the MCU.

I know how to work on my car but I am not able to because someone decided to lock it down.

You're overstating how easy these tasks are for many people. Doing brake pads/rotors or changing oil requires a driveway, some tools, and (for oil) a way to collect and dispose of the old fluids. Not everyone has access to those things - for instance, people who live in an apartment complex may not have the space to work on their car.

(Air filters are, admittedly, pretty easy.)

> it is very simple to change a brake pad and disc

I can attest that changing a brake pad is mission impossible level without the proper tools. The tools and experience are what make it look easy, for someone that has both.

Sure, everything you say was true for many folks 40 years ago too though! My point is, the processes haven't really changed for the common maintenance tasks over this period, people's perception of the difficulty certainly appears to have though.

Actually, in modern times you can buy an oil extraction pump off Amazon for $100, making oil changes so much easier than they were 40 years ago! A lot of [especially European] cars have the filter accessible from the top, meaning that you can change oil in 15 minutes in any apartment parking space by doing little more than popping the hood!

Changing a pad/disc/caliper isn’t “hard” but it’s time consuming and very messy. Most people probably don’t find spending 2 hours getting the car jacked, tires off, etc to be a good or enjoyable use of time!

These are all relatively simple TO YOU. You are not everyone though. Some people lack the mobility, strength or even time to do these things. Some people just don't want to get dirty working on their car. Some people don't have the space to do these kinds of maintenance.

Not everyone needs to know how to compile their own kernel, build their own furniture or clean their laundry perfectly. Everyone has their own interests and areas of expertise they want to delve in to. Now I can screw up a brake job working on it all day and rewatching YouTube videos wondering what I missed, or I can take it to a shop and get it done in an hour for cheap. That's just me though. I spent a lot of time working on cars in my youth and I'm just tired of spending my time on it. I don't like it and I am more than willing to pay someone who does like it to do it.

That is irrelevant to the argument he is making that things have not gotten harder in the last 40 years in regards to car maintenance that you can do at home.

His point is that the perception that car maintenance has gotten harder for the average joe does not match reality. Almost all of the things that need periodic on modern cars are more or less the same as they were in 1985.

I don't follow. Every time I drive my car I release the parking brake. On the cars with electronic brakes, you use a button rather than a lever. I'd do it the same way to service the brakes.

No, I think the other side has a point. If I were doing 10 services on my car, I would have muscle memory of a lot of things. If I am doing only brakes, and maybe another thing, I do not have that muscle memory. While the work may not be harder, the familiarity is gone for a lot of people.

BTW just before Covid, or during Covid, I took a car mechanic course from the local De Anza college - no hands on, so that's why I think it was during Covid. But after 5 years and no experience, I have forgotten except the abstract concepts. Then imagine people who never had to look under the hood -- ever.

I wish it took 2 hours. For me it's spend 2 hours shopping for the right part, finding it for a good price, and ordering it. Then spend an hour watching youtube videos for how to do it. Then spend 4 hours gathering the right tools, getting the car jacked, tires off, etc., then put everything away, and clean up. That's the best case. I could get the wrong part, my car looks different than the videos, I do it wrong, or break something. I recently replaced my front brakes. I maybe saved $400. I'm proud of myself. I kind of enjoyed it, but it's hard to justify.

A lot of electronic parking brakes do have a service mode. For most modern Fords, there is a procedure, as one example of many:

You typically need the piston fully retracted to replace pads, which very rarely happens just by disengaging the park brake.

If you are old enough to have changed a manual handbrake pad, you normally had to screw the piston back in before you could fit the thicker new pad with a "caliper rewind tool" even if the handbrake was off, the electronic parking brake service mode essentially does this for you, or unblocks the piston permitting a rewind tool to work.

FWIW, I've never found an electronic parking brake I couldn't rewind myself after a few minutes on google.

Stuff like changing cabin air filter or your own oil takes no additional space beyond the space already occupied by the parked car. You don't even need to lift the car to change the oil in most cases unless the car designers were massochists. Sure, maybe not everyone can get down on their back anymore, but that shouldn't be an issue for able bodied people.

You can change your oil wherever you parked the car. A way to collect the used oil is as easy as an old jug of milk, or the empty bottles from your new oil. Disposal involves finding an autozone or someplace similar and dropping it off for free. In terms of tools you'd need, a $5 dish from autozone to collect the oil, a 10c copper washer for your drain plug, and a socket wrench.

I’ve done oil changes decades ago but don’t bother anymore since I don’t feel like jacking the car up but using an oil extraction tool from the top does sound intriguing. Can you replace the filter from the top or does that require a jack? Also, does the filter need to be replaced each time?

A lot of people here are probably equally proud that they built a a DIY PC from scratch which I did many times. But just don't have an interest in doing any longer and screwed up a bunch along the way.

I also choose not to mow my lawn at this point. I'm perfectly capable of doing so but just prefer not to do so,

Huh. Interesting. I've never replaced the parking brake mechanism or (separate) pads myself, though I've done a handful of brake jobs.

On the cars I've worked on, the hand brake did not actuate the primary caliper so retracting the piston wasn't an issue.

Doing your own oil changes is not worth the hassle when considering the risk of a spill and the difficulty of legal disposal—unless you have a fancy engine that needs frequent oil changes.

Cabin air filter and wiper fluid, sure. Headlights and taillights used to be a no-brainer, but now those are often sealed LED assemblies and difficult to access as well.

I took several car mechanic classes from De Anza college. Great instructor, and I did do some hands on stuff.

But my primary takeaway was that this is hard & dirty work, and there are numerous ways in which you can make mistakes that ruin the car and/or endanger your safety, so generally paying a professional to do it is a more sensible way.

Of course, if you enjoy doing this, or have a very old car, or more time than money, the trade-offs are different.

I can also bake my own bread, make my own clothes and build my own furniture. But I choose to spend my time elsewhere.

What is so noble about changing your oil?

Air filters are easy, but so what? They are even easier for the mechanic when my car is in the shop for semiannual maintenance.

Which is true for a lot of things around the house. Although I got the whole house painted a bit ago because insurance was paying for it after a fire, there are some things I have experience with because I've done them a bunch of times--and often do them myself--there are others that I've never done. And may not have the right tools for and YouTube notwithstanding will probably take me a long time to do a very imperfect job.
