Well...it's an equal "concern" to me no matter how big my vehicle is. I'm as concerned with hurting others as much as myself.....I was speaking purely in terms of actual NEED. I'll be able to see behind me in the slingshot much easier than the bus. Even if I need to get all the way out to look,(doubtful) I will. If I don't think it's reasonably safe to go backward, I won't do it. Things could happen by surprise with or without a camera. I've never NEEDED a back up camera on any of my vehicles in all the years I've been driving, and quite honestly I think the option is too expensive on the SS......Who knows, maybe I'm just being an old guy. I suppose I NEED my smart phone now that I have one. Maybe if I had a back up camera, I couldn't then live without it.
