The Heathrow Pod is one of the most revolutionary airport transit systems in the world. Just using this personal peoplemover to nip from the car park to Terminal 5 makes you feel like the future has arrived.
With individual transport pods for each passenger (or group of around four to six people), you select your destination from a touchscreen before boarding and are whisked automatically -- no drivers! -- to where you want to go.
The current network takes you from Terminal 5, home to most of British Airways' flights, to two business car parks. The system uses an elevated track, similar to Brisbane's busway system, but with more planes.
Frequent travellers can only dream of picking up a pod from Terminal 3 -- where Australia flights on Qantas arrive -- and heading over to Terminal 5 for a connecting BA flight to Europe.
Your present option? A tired, smelly airport bus sputtering its way around the industrial landscape behind the terminals.
Each purple and white pod has two seats that would seat four reasonably comfortably and six in a pinch.
The stations at each terminal are modern and futuristic, with touchscreens to get you where you're going.
