Public transport won't substitute the need or desire for private cars. Improving public transport's impact will plateau at some point because people will always value the privacy and benefits of using their own private car.

You will never be able to create transport system where people take a bus in front of their door step, to the grocery store and back on demand.

You don't need to take a bus to the grocery store if said grocery store is itself in 5 minute walking distance from your doorstep (or have said groceries delivered)... I buy 90% of my own groceries from one of the 3 stores on my street or using deliveries, only take the bus for the rest, usually max twice per month and then I don't really mind that the bus only comes once in 15 minutes instead of "on demand"...
