Moved to Orlando last year down from Miami, which I thought had the worst traffic in Florida, and Orlando has shown me it is far worse and getting even worse by the day. Only in Orlando will there be traffic at midnight on a Sunday.
I am also very worried about traffic arriving into EU. While the Kirkman Road expansion is much needed, it does not solve the I4 problem. Anyone coming from the WDW area will have to take I4 and they will have to either exit at the 528 or Sand Lake exit (godspeed).
