Not all technology is bad. If we look at how much work per every liter of fuel todys engines produce compared to old ones, technology really seems to be a good thing. If it wasn't we may as well be all still using horses for transportation.
But some of the technology ruins the classical concept of car too.
Procuts represent consumers and todays consumer is far too lazy and stupid. Todays consumer can't roll window up or down or adjust seats or mirros with hands, todays consumer can't park car without help of different kinds of parking sensors, todays consumer can't use brakes or accelerator without computer adjusting braking or engine power. Today's consumer can't or isn't willing to do much at all. And today's car manufacturer takes all that into account and makes cars that allow to drive without driving the car. And driver gets alienated from the machine.
And than there's the health and safetly issue. Incresingly demanding passive safetly and engine emissions standarts are introduced and that requires further complexity of vehcile design and, as a result, cars get heavy.
Design and beauty suffers too. There are crumple zones and impact areas to worry about, and, to give the next generation models futuristic looks, designers often try too hard and end up with something that can never mach the clean-ness and elegance of a car like this:
