What you really have to watch out for when driving in Orlando are the tourists doing dumb things and the aggressive driving locals doing dumb things,As far as amount of traffic I've driven in more than enough places that have worse traffic than Orlando,in Atlanta during rush hour every single car in the expressway was doing 85mph and basically tailgating each other,I've never seen that and it kind freaked me out not being used to it as I live in S.Florida which also has crazy traffic but you have people doing 90mph swerving in and out of others doing 60mph in a 70mph zone.New York is insane as well and I couldn't imagine trying to cross the Bay Bridge in San Francisco every day in rush hour it took me about 30 minutes to go about 2 miles to get to the bridge and it appeared to just be normal traffic.Comparing all these places to Orlando I realize Orlando isn't too bad and as someone said there are other options like jumping on the 417 to avoid I-4 or taking a ground street around it,but I have to say I always keep my eyes open in Orlando as you're likely see more dumb moves than in other cities with more traffic.
