Earlier quoted context omitted.
The only thing that constantly improves and is really worth considering is safety. I am not even saying about active safety features but the passive ones. They are also in constant development.
But these are sometimes making it safer for the occupants at the expense of the rest of the environment (think smaller windows and fatter A pillars making children harder to see, or strengthened soundproofing making children harder to hear.)
Are children really harder to hear? Old cars were louder. How much sound did they cover up just with noise? How much more could you hear in an old car compared to a modern electric car?
