Too much tech! If people paid better attention, they wouldn't walk behind a moving vehicle. And the driver should be looking as they are backing. Not at the camera, but out the back window. If everybody did what's been standard practice for backing up for the past 100 years, we'd all be fine.
I know I'm not the only one that notices all of the tech on vehicles today are advertised to show what the car does FOR you when you aren't paying attention. Drop you phone and you reach for it, lane assist puts you back in your lane. Zoning out while driving and forward brake assist will brake for you when you approach the car ahead of you. Start backing up without looking and auto braking takes over when there's a person there. Start changing lanes without looking in your mirror or looking over your shoulder and the vehicle corrects.
All of these gadgets are being designed to protect us from ourselves because people have lost the skills required to drive. And they don't road test kids for driving tests or teach them how to drive anymore, so what should we expect?
