Do cars need back up cameras?

I'm 17 been driving since june i had a ford focus but just got a ford fusion its a lot bigger

i was thinking about getting a wireless back up camera

i'm not sure if i should or not since i always see the back up cameras in suvs and trucks

You don't need one, I've never even used a car with a back up camera. But it probably does help.

You tell me - If you're decently trained at backing-up, you should do it using only your side mirrors. Also, if you live in a place where there are lots of neighborhood kids running around, wouldn't hurt to be safe. I personally wouldn't even consider it.

No. You don't "NEED" a back up camera. You can get one if you want though.
