Think of a world where there is no ride-sharing; people are driving themselves to work. You now have 30 people being served by 30 cars. Those 30 cars are only served 4% of the day; 96% of the day, they're stored somewhere. Around 20% to 30% of our land is taken up just storing these hunks of metal that we drive around in for 4% of the day.
