Talk about a niche market. Honda recently announced that they will begin equipping all new hydrogen fuel cell-powered 2005 FCX vehicles with a navigation system that will include data on the location of all hydrogen refilling stations. How many stations would that be? A whopping total of 26, just nine of which are outside of California. Given that, we somehow suspect that FCX owners have long since memorized the route to nearby — and distant — hydro stations. Oh, and how many cars are we talking about? As of this month, Honda has a grand total of one retail customer for the FCX. So, Mr. and Mrs. Spallino, enjoy your new navigation system.
