I see the feds want breath analyzers in new cars. If this is allowed I think it could clear the way to ban/jam cell phone use while in a moving car or in a car period. Therefore- In my opinion I don't think breathalyzers in new cars will pass- because if you cant ban one how can you ban the other. Both are dangerous but cellphone use has been deemed a dang near human right. I see distracted cell phone drivers EVERYTIME I drive. I do not see drunk drivers every time I drive.
