Today my Prius arrived at the local dealership. I'd been waiting for it since about last May.
I've got to say that the biggest pleasure is in using something extremely well-designed. The keyless entry and ignition system, so that you don't need to fumble for keys in the rain. The built-in Bluetooth. This is a car built by engineers who worked hard to understand how people actually use their cars.
And, of course, the hybrid drive system. When this car stops at a stoplight, it stops. No idle motor. Nothing is consumed. I could probably wedge the brake pedal, leave it there for a week, and then get back in and drive away without any problems. Most people measure efficiency in terms of miles per gallon, but consider how much time, in the course of our driving careers, we spend stopped at stoplights, stop signs, in traffic, or in drive-throughs.
So after six hours I still love it. Of course, it's been raining steadily all evening, so I've only gotten to drive it around a bit and sit around in the driveway making "vroom vroom" noises.
Ok, I didn't make "vroom vroom" noises. But only because I was imagining it in electric mode.
