Are Hybrids growing in the US?

I currently have a hybrid. Good for milder weather. Not good for serious heat or temperatures much below freezing. They are great to tow and have plenty of room. I like the open feel when the windows are opened up.

Most people are more comfortable closed up with hard sides. They feel more secure and can moderate the temperature better. Hybrids will probably always be a niche market unless there is some more innovation.
