Why don't I own any Diesel or Electric Vehicles?

The first one is easy. I had a 1971 VW Rabbit that I bought for my son and used it some too that was a diesel Rabbit and probably the most gutless car I have ever personally driven. For example, if you went up even a 1% grade you would have to down shift it into 3rd gear to keep going. You couldn't even keep it in high gear on a 1% grade which is pretty bad. Then I didn't understand how the engine oil in the crankcase could become carbonized from the diesel. So, when we traded this car in on another car I realized I didn't know enough about diesel engines to actually own one even though I had worked on Gasoline engines since the 1950s with my father when I was a child until around 1995 when I married my present wife and she preferred buying 5 to 7 year maintenance programs from her car dealerships to make sure the car was properly maintained. Since this was the way her family did this I realized I didn't have to work on my cars all the time to keep them up myself and besides I was 47 in 1995 and ready for a break from working on my own cars all those years.

An Electric Car is an entirely different story. Though I like the idea I don't want to expose my family or passengers or myself to any more electrical fields that can cause health problems over time. The main thing might be something like leucemia or brain cancer eventually especially for young children exposed to these electrical fields from either the generation or use of power like in hybrids or just the use of the power in totally electric rechargeable vehicles. So, even though I like the idea of saving gas money with an electric I'm not willing to sacrifice my health or my passengers health to achieve this.

So, instead I try to buy reasonable mileage vehicles always. For example, I got a Tundra in 2011 that gets 20 miles per gallon because the 8 cylinder engine can do that in overdrive if it's just me in the truck long distance.

So, I try to get vehicles that get 20 to 30 miles per gallon on the road rather than get an electric or diesel car.

Besides, on a purely logical basis a hybrid makes a whole lot more sense than an Electric Vehicle especially if you want to drive it anywhere outside of California because of trying to find recharging stations in other states. 

But, I suppose if you ONLY were ever going to drive in California you might be okay with an all electric Vehicle because there ARE enough charging stations in California if you are very careful where you are driving too along the way and the timing of it.
