Actually, having spent my driving life on Los Angeles freeways, I found central Florida to be absolutely terrifying. From the minimum speed signs which didnt seem to prevent people from speeding along at 25 mph down I-4 to the odd habit of people stopping where the connector from the Beeline merges onto to the Interstate, the trip from the airport to property was more stressful than the East L.A. Interchange on New Years Eve. I will not even start on the criminal nature of toll roads.
And the area around WDW has long been, well, lets just say a major source of revenue for the local governments, especially from cars with out-of-state plates or the old rental car tags (all the rental cars in Florida used to have a license plate that had a Y this lasted until carjackers started preying on people leaving Miamis airport). For kicks one time we brought a radar detector with us the readings were so high we thought we could have cooked microwave popcorn in the back seat.
In the early times the accident rate on WDW was significantly lower than any other metro area with the same traffic density. The road system was designed in the 1970s using all the high speed overpasses and flyways that really make a roadway work. The system held up very well until the original master plan was scrapped and they went to stoplights throughout property. Theres nothing like an intersection no matter how well marked to cause accident rates to soar. Combined with the abandonment of a true internal transportation system that shoved thousands of cars and scores more busses onto the roads I do agree that the roads on WDW are no longer safe.
Additional enforcement isnt going to improve the condition on the propertys road. They need to have much of the traffic removed from them (by creating a real transportation system) and the roads themselves need to be realigned to fit new development patterns.
