Impatient nasty aggressive drivers

FLORIDA...Drive where every 4th driver is over 80 can not see over the dash, drives into your lane and no matter how loud or long you hit the horn acts like they do not hear it and just keeps on coming..Now the out of state older drivers coming down not knowing where they are going..Oh, and when it rains they drive 35 on the 70 MPH on I-75 OR they all are stopped under the over pass like they have never seen rain before!!...I could use a Machine Gun mounted to my Hood..
