Yes, there have been massive improvements. so much so that many people take these as a given. Here’s a small few off the top of my head: - power steering (most people would struggle to drive a car without it) - anti lock breaks - suspension systems - fuel injection - multi gear transmissions - airbags

Now that I think about it I’m not sure I’d put the change from gas to electric as more revolutionary than a number of these seemingly mundane improvements.
