You are spot on. My parents live in Houston and during a past hurricane they were told to evacuate. They made it 2 miles from their house in 6 hours. When Houston floods, there are often not many obvious routes to take with passable roads. They eventually turned around and went home where they would be safer than stranded on a freeway. I was in Tropical Storm Allison in Houston. Within a few hours that I was at a concert, we went from light rain to the nearby freeway exit being 20 feet under water. We spent the night in a medical office building because we could find any passable route out of a 2 mile radius. My car was swept away into a drainage ditch and filled with water. People are better off staying home or moving to a nearby high-ground area. Than riding out a hurricane in a car in traffic.
