We need a system like that on the west coast. The major N/S roads are parking lots. Very few major business to the north, so they all travel south- Tampa/ St Pete even Orlando. Have a neighbor who drives to Orlando daily. A 50 mile stretch from my area into Tampa can take up to 3 hours.
Brightline is planning a Orlano to Tampa leg but it's a long way off.
One of the things about Florida travel where I'm at is that there is no good way to get from the East Coast to the West Coast. It's mostly these dangerous two lane roads with a lot of slow truck traffic that people have to pass. Plus I have a big lake to go around.
