That’s a sentiment I get every day when teaching maths. Many do not value maths because they can’t see any immediate benefits. What I’ve learned is that you never know what knowledge you might need in the future.
Knowledge is knowledge and everything is of some value. Maybe not the greatest value at all times, but some value. One should strive to have as much knowledge about as many things as possible.
The problem is that modern cars are shitty. It doesn’t matter if it’s a petrol, diesel or electric car. If I can’t repair it myself, it’s a poor quality car. The fact that you might need specialized paywalled software to remove error codes after fixing the car is just awful.
Most people I’ve spoken with that claim that they don’t like electric cars eventually agree that they don’t like modern cars. Mainly due to how closed everything is.
