That is ludicrous. We've only had cars for a hundred years.
The fact that it's difficult is BECAUSE we built cities around cars. Schools normally have districts so that they're nearby to the kids, if your kids school is in another suburb then frankly that's your poor planning. If you set up play dates with kids two 'burbs away, again, why did you do that? Places like Japan have no issues with no or low car families, the kids take public transport, walk, or take their bikes. You can ride your bike with them or join them for the train ride if you want to make sure they're safe, but the idea that kids need to be transported around in cars is ludicrous.
> but often "time" is a critical factor and you need the flexibility that a car offers.
Public transport and biking is often faster than cars in denser car centric cities, and good public transport is on time so you can plan accordingly. Not all cities have good public transport, I get that, but that's the problem we need to solve. We've already tried cars, it's not working.
The issue isn't that we need cars, it's that we need a better city built around moving people without cars. You're looking at the problem in the wrong direction.
