Individual autonomous cars will solve all transportation issues. What's that? Trains? Trams? Efficient urban fabric? Things that Tokyo, gasp, already has? Bull.
There are about 50,000 taxis in Tokyo. What are they doing there?
I don't know but Tokyo doesn't need more cars on the road, that's for sure.
Trains close at midnight. Taxis are mainly used after then and for more affluent people or people in emergencies / special occasions.
In my opinion Individual autonomous vehicles will solve most transportation issues not Individual autonomous cars. Currently to transport 60-70 kg person we are moving 2 mton machines ie cars. And those 2 mton machines are in use for just 30-60 min a day.
