I understand what you’re saying. But the car orientation makes it great for workers and families in many ways. Irvine has high speed limits that make it quick to get around. Parking is everywhere. The walking tends to be within destinations (like parks) rather than around town in general.
But apart from that the city is just run well. Everything is clean. Amenities are maintained properly. Public safety is high. Schools are great. It’s why so many like settling down in the area once they hit their 30s.
