My thoughts exactly. Brightline isn't the commuter rail line that runs in the Northeast, it's going to be scheduled and infrequent. Cars will continue to rule in Florida. You can't live there without one. 4, 95, and 75 are absolutely choked with traffic in any sort of metro area. The toll roads in and around MCO are the best way in and out, but they have issues too and don't go far in every direction. If you want a quick drive to work, consider finding a place close to one of the toll roads (this is no secret, there are neighborhoods popping up everywhere that used to be scrub and swamp).
Like Slip said, it's getting crowded there. The secret is way out and everybody is moving there from high tax structure states and it is creating a lot of issues that Florida really hasn't seen yet. My wife and I highly considered moving back and relocating to the space coast, but a couple of long visits with family have cured us of that notion. My family just sold all their waterfront property that they have owned since the 60's, made a tidy profit, and have mostly gotten out of dodge. Insurance, crowds, and housing costs are creeping way up and making it just as expensive or even more expensive than many places that offer a lot more. Frequent hurricanes over the last two decades have made owning a house on the water untenable unless you are extremely wealthy.
There are still a lot of great spots left to move to in the state, but they aren't anywhere near Orlando. How long before they get overrun too, though?

As I have said before many times, I love Florida, it will always be home, but it's getting ruined by its own success.
