Ever read thelastpsychiatrist? The website is dead now (and he may be too, for all I know), but he was on the money when talking about why a specific amount is paid by the state to the unemployed - it's the exact amount of money that would stop the idle masses from burning down the city.
You don't understand it now, but you will if we had a transition to completely automated driving in a short period - those millions of unemployed drivers, that are now never going to be employed, are a risk to the city.
