text: An amazing advantage that people can can from limiting the usage of cars is less drunk drivers, or even none. If there's less drunk drivers, there's less car crashes and less deaths. Everyone understands that you have to be 21 or older in most states to drink alcoholic beverages. The big adavntage out of this is, if older people were to get drunk, they would be forced to call a cab, or even walk home. Their not putting noone else's life in danger, and this would lower the crashes and death fatalities per year.
