Compared to Orlando International Airport (MCO), Tampa International Airport (TPA) is usually a breeze. Much of the difference is due to size. In 2017, MCO served 44 million passengers across 129 gates in four airside terminals. TPA had just under 20 million passengers that year across 59 gates in four airside terminals.
TPA just opened a centralized rental car center. Instead of waiting for a bus set up by your rental car company, you'll board an automated tram. The term "centralized" refers to the fact that most rental firms are in one place, not that the building is central to the airport. It's actually quite a ways away. This YouTube video clocks the trip at about 4 minutes 10 second.
THANK YOU for posting this.

So interesting, a centralized rental car center served by a tram instead of taking a shuttle bus!
