I think you don’t have enough exposure. Yes yes road design great. Bike lanes great. Higher density great. It still does not solve the problem in American. My own cherry-picked example. The DFW metro area is half the land size of your country. A lot of it is already built up and it’s massively sprawling. On a normal commute from any given 5mile radius is going to be highly unpredictable, people are going in every direction. It’s extremely hot in the summer and it rains. Huge change management problem that you will not overcome. At the end of the day it’s hard to make a comparison from a country where a city by land is 2% the size of Dallas.
Last mile is an incredibly challenging problem in the US. It is typically not economically feasible even ignoring the culture change management. Short of rebuilding entire cities and forcing people into high density buildings most of this will not change. Now if you can make really amazing autonomous vehicles that can actually solve most of the last mile problem and introduces the ability for cities to create mass transit that is an interesting solution. Even if use for the full commute those have real potential to eliminate congestion as after all it’s usually some combination of accidents and poor driving. Parking those at night? That is no issue at all.
