  Heathrow pods are essentially driverless electric cars, which means that they are better for the environment than petrol cars.
  
  The question now is – where would the flight be to and could it be avoided/replaced by a train journey? 😉

  Yes they look really cool!
  They are powered by batteries and are 70 % more efficient than cars which is quite impressive- hopefully they will start to use them in other places too and I can have a go!

  I have not heard of them but from Ola and Megan’s responses, they sound cool.

  Same as Mzamo, I havent heard of them until now! But they sound pretty cool to me.
