Shopping is hard without a car. You can only buy a few items at a time. This works great if you have local bodegas all over the place, but not so much if you depend on supermarkets.
If we enabled more people to bike for our commutes and just use a driverless car (or a taxi/Lyft) for shopping, car ownership would be much less essential, and car rush hour would be a thing of the past.
I just hope they put a bike rack on the Cruise cars. :-)
The end result is 'food deserts' where one has to have a car to drive out to get food.
