well obviously My aunt has a modern car that reads the signs for you. Where I live there is a highway in the middle and normal road on the outer side. That piece of crap slows down to 70 km/h from 130 when it sees the sign that belongs to the other road…
However, not all tech is terrible. For example, parking cameras, gps, cruise control are useful
Edit: I think the current toyota land cruiser 70 series sold in australia is at the sweet spor of technology
