Retailers hit hard by online shopping will sell their parking lots for $millions when driverless cars become popular. They can cruise the streets while their owners shop.
After years of being hit hard by online shopping retailers and shopping malls will shed the expense of large parking lots in prime urban locations. They will be set up with drop off and pickup zones for customers who will then send their cars back home or to cruise on the road until they are needed.
The efficiency of the driverless cars will prevent traffic jams and eventually roads will be build where the cars can drive a circuit until needed. The land will be used for housing, businesses, parks and entertainment.
Other things these driverless cars will change include: insurance as there will be few accidents. The need for drivers licenses and testing, traffic cops, road signs and even traffic lights. Governments are determining of the lost revenues are off-set by the savings.
