The only person whose commute time I know off the top of my head right now commutes by car in 15~20 minutes, so 30~45 minutes is not great.
People spend far too much of their time working or commuting as it is. The last thing they need is even more commute time.
Well, its not like the six lane highways going in and out of cities like LA are void of traffic jams. Cars are not a real solution to lower commute time, especially since they take a lot of space, so cities need to be much wider, just holding streets for cars, instead of having the building closer together.
How do you deliver goods to and from a business inside a city, if not by truck? You still need streets for trucks.
Yeah, but for those trucks you can do with one or two lanes, where you would need 4 lanes otherwise to accomodate the car travel. In my country an average supermarket needs about 2 trucks a day to supply 5000 people. So thats 12 trucks a week or roughly 420 people supplied by a truckload. Assuming people to go to the supermarket once per week, and 2.5 people supplied per car, that is 168 cars for every truck. And a truck doesnt take more space on the road than maybe 4 cars.
So in our example, with favourable assumptions for cars (e.g. you'd expect grocery shopping a bit more often than once a week, and many household only have one or two people) you need 42 times the road space for the car traffic of the supermarket, compared to the truck traffic.
I live in an inner city in Europe. I have two supermarkets in 5 minutes walking distance, 4 supermarkets in 10 minutes walking distance, and another 3 just one trainstation away (also about 10 minutes door to door). There is no need for a car and the supermarkets do perfectly fine, with a small road connecting them.
