The UK also has a poor record on trains (ironic as we invented and developed them). Part of the problem in the UK is that the network is so old its not laid out for high speed services, so to achieve this we need all new track. The UK is finally creating new infrastructure like the new Crossrail line that will connect suburbs and towns east of London with those in the west of London with a service to Heathrow airport. However this has been needed since the 1970s and was proposed even earlier. High speed inter-city is beginning with HS2, but the fate of this is unsure as the price tag keeps going up.
If we take a step back for a moment though, look at whats happening in transportation; self driving cars. I cant fathom why self driving trains are not already in place.
