More importantly, cars today require less service, use less fuel, pollute less, and are far less likely to kill you in a number of common accident scenarios. It was rare for a 1974 engine to go 100,000 miles without needing to be rebuilt, even if you religiously changed the oil (every 3,000 miles) and otherwise kept it up. You would almost certainly replace a water pump and alternator in that first 100K miles. I am now on my third car that got to 200K miles without needing any major engine maintenance at all, the oil is changed every 7K, and the car reminds me when I need to do that. The second of those cars went to the scrapyard because I got T-boned (by someone looking at their cellphone instead of through the windshield -- another issue) and I walked away. I only realized after the car got towed and I looked it over how carefully the roll cage had folded up to keep the jeep that hit me out of the passenger compartment. If I had been driving my old 1972 Buick Skylark instead of the 2003 Toyota Camry, I'd have been dead. And both of my current cars get nearly 40 MPG, an unheard of figure even for a compact in the 1970's. Modern cars could certainly be even better, and the next step might be hybrids and EV's, but they have improved a great deal over the course of my life.
