What's your bike rack set-up like?

I just bought my dream car Saturday and I'm trying to figure out the best way to add a bike rack to it. I drive my bike to the trail to go riding so it's a necessity.

I have a new-ish hitch rack so that's the direction I'm leaning but when I look up hitches online I see mention of needing straps to additionally support things. I've never seen a hitch rack use straps so I'm totally confused by this.

A roof rack doesn't appeal to me at all. And I'd love to continue using my new rack (I love it!) but the strap thing...
