You can drive to France from the U.S., but you have to go through Canada. Two islands -- Saint-Pierre and Miquelon -- off the coast of Newfoundland are part of France. (Okay, they're islands, so the last leg of your trip would be by ferry.) The official currency is the Euro and the islands are part of the European Union. U.S. citizens need their passports (and a visa if they plan to stay more than 30 days.) Electrical outlets are 220 Volts, 50 Hz and the physical sockets are Standard French, so you'll need adapters.
