Yes. And over the past three decades there have been a lot of advancements and improvements as well as a general push for larger engines for both efficiency and “number go up” horsepower. Also structural design to increase safety in the event of a collision.
The reality is that there has always been stuff you can repair just by popping a hood and stuff you need to prop it up for. And there have always been people who decide to reach under the car to drain the oil and pollute their local sewers.
Any form of engineering is a trade off. And if you compare “under the hood” for a car from the 90s versus one from the 2020s, it is going to look a lot more packed. And, at some point, having super easy panels to open up once or twice over the lifespan of a vehicle is just not a priority for anyone other than someone on the internet looking for something to be angry about.
When it is a case of needing to go in for maintenance to re-approve all my parts? Fuck that noise (also why anyone who ever plans to do electrical work should get one of those code readers to reset the error light…). When it is me being expected to do something incredibly basic like “prop up the car and remove a wheel”? If you aren’t comfortable doing that then you aren’t comfortable “working on” your car.
