When travelers park, they display a document that shows the international symbol for persons with disabilities, as well as the name of the holder of the document. Starting January 1999 a traveler in a ECMT country with a parking document can get the same parking facilities as a citizen of that country, provided the traveler is from an ECMT member country or from an associated member country. Since an increasing number of motorists with disabilities are coming to Europe from the United States and Canada, the resolution recognized parking permits issued to drivers from these countries as well. In London taxies and even some buses are adapted for disabled persons. You may find it even cheaper and advantageous, since it forces you to mix more with the local crowd.
Parking is very hard in the above-mentioned cities.
Some cities offer wheelchair-adapted buses . When possible, avoid flights if the distances permit travel by car. Airport procedure and car replacement may take a long time. Upgrades are very nice for most drivers, but may be problematic. Upgrading from a spacious Opel or Ford to a sporty BMW or Golf may be fun to drive, but hard with a wheelchair or difficult to get in with long legs.
