Re: Technology to save lives
More and bigger public transport won't work. You can't get a bus down my lane and it's too far to walk to the nearest bus stop even without shopping so I just get in the car.
A fleet of publicly owned driverless cars may work if there are enough for them to be treated as cheap taxis and they may be better for the environment if there are so many that there is always a free one nearby (that's why taxis are so bad - they spend half their journeys with just the driver i.e. zero passengers).
