You'd think cars, at least, will be built under the assumption they'll typically have to be repaired rather than replaced.
They used to be. Go back far enough in time and you could climb up under the hood into the engine bay to work on it. All that went by the wayside to get smaller packaging, lighter weight, and better fuel efficiency.
Now you need special tools or special code readers to solve/diagnose all vehicle problems. The large scale farmers are dealing with this now with the large combines and harvesters needing a tech with special equipment to read all the codes where the older tractors from the 70s and 80s can be repaired.
Uncle had a truck, I dont remember what brand or what year. But I do remember him climbing into the engine bay and sitting on the front tire well to work on the engine, because I was on the other tire well watching him. and we both had absolutely loads of room to move around. more so me, being a kid, but he was a big man and he still could slither around everywhere in that engine bay to get at what needed got at.
vehicles, especially trucks, used to have an insane amount of space under the hood for working on the engine.
I used to think that until I worked on a friends 70s muscle car. The spark plugs on the drivers aide are a pain because the steering shaft runs directly down beside plug 5 and 7. But overall all the plugs and boots suck because they are tucked under the exhaust manifold.
