I've never driven drunk in my life. Why should I pay more for a car with this new device?
The solution is simple: get caught driving drunk, pay a $2500 fine and lose your license for a year. Get caught driving on a revoked license, spend a year in jail. Kill someone by driving drunk, spend 12-15 years in prison for negigent homicide.
End of problem.
I agree. This is a presumed guilty until proven innocent scenario. Theny you can blame the sensor.
Perhaps they should use them on city busses or passenger planes.
