Honda, IMO, is not true competition...apples and oranges (at least to some degree). Honda uses IMA (integrated motor assist), the car can't run solely on electric power. The engine is always running. Toyota can run on just electric power (at low enough speeds or on the right declines). That's nice, especially living in Colorado going up and down the mountains. I am a little concerned about the HP of the 400h, if it is like the Prius. I suppose you can't have a muscle-car that is also a high-mileage vehicle.
Too bad about the HOV exception, I have heard similar issues in other states as well.
