Here in the UK the Ordnance Survey continue to show a bridleway (path for horses) crossing Blackbushe Airport in Hampshire. It's been like that for decades.

In the UK every socket outlet can deliver 3kw (13 amps @ 230 volts). 3kw is normal for kettles which can boil one cup of water in about 90 seconds from cold. OTOH hair dryers don't need that much power because it would be ridiculously hot. For the same reason tumble dryers are usually only 1kw.
