Anyone that doesn't believe in the cameras and has access to one I can show you with a real simple test like we used at work how great they are. The Odyssey is putting them in the mirror like shown above unless you get the navigation package then they do it in the dash. I assume most companies will do this. As for the back-up alarms, children and inanimate objects often will not respond to these. I cannot tell you how many times during our research we had soccer moms jump in their vehicle hit the garage door button and start backing up. Half open doors, bikes, weed whackers, trash cans, you name it we saw it get hit. Then we also so the ones who stopped just short as it popped into view on camera. I think for the general public these are going to save lots of money. How many times have you heard of or been the victim of someone backing into a parking spot and hitting another car? This will help that too.
