You make a good point John. The vast level of complexity being added is possibly the biggest unsung blight.
Cost of manufacture to us and to the resources we have.
Cost of lugging them around
Cost of repairs as they are all "modules" which just get swapped
Cost of end of life dismantling, like that's going to happen
Each seat with two/three motors plus, heating, plus cooling, plus massage, plus load sensor for seatbelt. I lifted the Tillet out of the Mog with one arm and we were lovely and comfy around Europe for a couple of hours most days for two months.
Scope creep on features has become a blight on the planet. I know that makes me a charlatan given I always buy overloaded toys but there needs to be a mid point between a decent Dacia and the complexity of a Tesla.
Self driving is going to raise this to the next level of electronics and complexity as well. LIDAR sensors being used on some of the cars cost a packet. Volume may reduce this but it is going to remain a shocker as the car ages or gets into an accident and these need reaplcement. Yet another hike in insurance costs.
