Why has the telephone/computer technology advanced more than the automobile?

Computers are electronic devices which follow Moore's Law. Cars are mechanical devices that power and move things. They are simply not related. It would be like asking how come computers become so much smaller and more powerful but my furniture still weighs and works the the same as it did 100 years ago? It's just not related.

Cars have gotten a lot faster, safer, and way more comfortable. I'm not sure if you've ever driven in a car from the 1920s or 1950s, but I am pretty sure you would say we have come a long way (comparing it to the days of having huge computers in a room). Riding in an average car from 50 years ago is just a miserable experience.

I've noticed from several of your posts that you are eager to point a finger at gas companies for being evil or somehow suppressing some secret or advancement. The reality is that gas companies are international, they are from every continent and every country. Over time, many go out of business or fail to survive independently. Many, if not most energy companies that existed 40 years ago don't even exist any more. They have every incentive possible to try to our-compete their competition and advance technology. There is no reason for "them" to keep "cars at bay" or participate in any other massive conspiracy theories.

My car is pretty smart...I'd say auto's have advanced a lot too. I have blue tooth...that picks up my phone as soon as I get into the car...no wait...it picks it up 20 feet from the car....I can use the internet...GPS...all kinds of things...installed a DVD player for my grandson....my seats even have a butt massages of all things that I accidentally discovered...nope, I would say cars have come a really long ways....push a button or wave my foot and the trunk opens...push a button and the car starts and turns on the AC or heat...I could almost live in my vehicle...can't say the same for my phone. LOL

I remember my first car, a 1977 Oldsmobile Toronado. It was gigantic, and got about 13 miles a gallon. Even at gas prices around a buck, that was expensive for a high school kid to run. I now have a 2014 Chevrolet Impala that comfortably seats five adults and gets over 30 miles a gallon on the highway, about 25-27 in the city in a car with over 300 hp.
Just ten years ago that would be unthinkable.
