> It would be a misconception to look at your standard internal combustion car as a fundamentally mechanical device. Today's cars are some of the most complex electronic systems mankind has ever made.

As a car restorer, mechanic and enthusiast, yes. This is also why bringing a car in for service has ballooned in cost over recent years. Oddly, it’s become remarkably _easy_ to chase down a problem in a car because the systems will just tell you exactly what’s wrong. Now it’s just a huge time sink to actually fix the problem because it’s probably buried deep in the gubbins of the car and the parts are very costly.
