New interstate speed limits

First, check the rating of your tires, never drive faster than your tires are rated for. Even driving at their rated maximum could cause a problem, if they are older. Second, at least in Florida, driving with your hazards is illegal and could get you a ticket. That being said, IMHO driving less than 10 MPH of the average speed is causing a dangerous condition. People on cell phones, texting, or just dreaming will come up on you to fast, they then will slam on their brakes, change lanes, or crash into your rear, any of which could cause a major accident. It amazes me how many people do not know how to drive correctly on the interstate. Law enforcement should be increased, and tickets given to those who exceede safe speeds, or drive to slow! Those people should be required to attend a course on safe interstate driving, merging, keeping to the "driving" lane unless passing, driving at the posted speed! This would make interstate driving safer for all!
