We are fortunate to be using the Elizabeth line between LHR and Paddington, but otherwise it looks like we will do a lot of walking, Lime scooters, and/or Uber. Of course you can't take even a carry-on while using a scooter, but on the bright side walking is good exercise lol.
But what about folks who need to get to work or important medical and other appointments? Taxis and Uber can't service everyone, and a lot of folks are not suited for Lime scooters and bikes, let alone walking for miles.
I realize the situation is far more difficult for residents. As for me I guess I'll book a taxi or Uber for the "too far to walk" trips.
