First of all this "simple" car may end up being more expensive. Doing a lot of the things the old mechanical way requires a lot of labor and labor is expensive nowadays. Having to use turning wires and vacuum tubes for instrument clusters, and a bunch of pull wires for controls... Not only would that be expensive it would require skills and equipment long lost today. Oh and the wind shield wipers -- it is possible to power wind shield wipers mechanically but those were some very complex rube goldberg type mechanisms.
Furthermore, this "simple" car will not last very long. People have forgotten that nowadays, but in the old times of "simple" mechanical cars, cars used to break down much more often and require much more skilled maintenance.
Most people would not know how to use it. Do you think people will be able to handle an unassisted wheel? You know, actually use their muscles to turn the wheel when parking? How about unassisted brakes? You get into a dangerous situation, you slam on the brakes and then it turns out that you have to use your muscles to actually apply sufficient force. How about even getting into the car without a radio key fob. I very much doubt the majority of people will even know how to lock or unlock their rear doors without a central lock/unlock key. They will probably just leave their car unlocked.
But most importantly, it wouldn't sell. Cars nowadays sell based on electronic features. You can see that from the commercials. Even fairly advanced features like navigation and parking sensors are considered a must have now.
