Over the past 2 decades or so, the range of EV batteries has advanced from about 70 miles/charge to maybe 400-500 miles/charge ... that's slow linear growth of about 20 miles/charge/year ... far from revolutionary, exponential growth.

Actually, the time span of electric car batteries dates back to 1827 when Hungarian priest Ányos Jedlik built the first electric motor; the next year he used it to power a small car powered by a non-rechargeable battery. The original Studebaker Electric cars, which were produced from 1902 to 1912, had an official advertised driving range of 40 to 70 miles per charge depending on the specific model, battery configuration, and driving conditions. Thomas Edison bought one of these second-generation 1902 models and drove it for over two decades. EV batteries then went almost another 100 years without significant improvement in range. Evolutionary? ... no, turtle growth, Dear Watson.

An example of revolutionary technology and exponential growth is in computer chip technology, incorporating both CPU computing capability and expansion of solid-state memory/storage, all while greatly reducing size and power consumption. Rotating hard drives have also experienced exponential capacity growth, from kilobytes to terabytes and beyond.

Now, I know you think I am an obsolete fossil, but my ability to think and reason actually improves as time passes. I pursue knowledge and learning daily. I was not selected to be an Adjunct Professor at a major university for 13 years because I was an intellectual dunce. I am very modern and futuristic in my thinking. I have all of the modern playtoys, amenities and necessities of interest (motorcycles, automobiles, electronics, appliances, medical care, etc.), but my discretion weighs futuristic trends heavily as to feasibility, sustainability and affordability, as well as to impact on mankind. I have not as of yet recognized EVs as a significant advancement for mankind without associated unintended consequences. Time will tell.

I'm not saying that I would never acquire an EV, however it is unlikely in the next few years unless I win one. As I mentioned to Ken in a recent discussion below, I have had vehicles and motorcycles that are faster than his Tesla 3. I do enjoy fast vehicles, but it's not a thrill to which I am currently addicted. Almost 30 years ago, I made a quick mad dash down I-65 at 140 MPH in my earlier Mercedes Benz, and that was my last foolish stunt. Shortly thereafter, at a BMW dealership, I saw a picture of a M5 that had gone over 150 MPH, went airborne, crashed and dashed to pieces. Traffic laws, better detection and enforcement, congestion and unpredictable drivers have taken a lot of the fun out of fast vehicles.

My next vehicle will probably be something like a MB CLE 450 AWD Cabriolet or AMG CLE 53 Cabriolet. Fun, stylish, peppy, respectable 0-60 in 4.2 sec. I will continue to keep my "Chevy-badged" Cadillac XT6 as long as it looks new and remains reliable ... it is no worse for 8.25 years of wear ... remarkable. In fact, Cadilliac would have been smarter to have incorporated more planned obsolescence like BMW and Mercedes do. I have had many of the luxury vehicles since the 1960s (Lincoln, Cadillac, Buick, BMW, Mercedes, Peugeot), and the XT5 is the best all-around vehicle of the lot. I would buy another one when the time comes.
