**I have done some desk-work and put together a few assumptions to see how self-driving transport adds up. What are the problems with self-driving cars or the idea behind them?**

Without leaving the kitchen table, I was able to identify some conceptual problems with self-driving cars and ways to improve the efficiency of car use.

If a car drives on average 12,000 miles per year and does an average of 60 miles per hour then that means 200 hours of driving per year. (Cars are spent after just 1400 to 2000 hours of use).

The occupancy rate in relation to hours per year is very low. There are 8760 hours in year. Cars are driven for 200 hours a year, typically. For 8560 hours a year a car is unused. Thus there are 43.8 times more hours of use available than are used each year. If you drove all year, you would still Continue reading “17.5 Billion Hours a Year”
