Provide a stronger warning when the trunk is open and backing up.
I was ready to back out of the garage. My wife closed the trunk lid, heard a beep (as did I) and we started to back up. Noticed (what I thought was the driveway complete with the two white stripes) and turned to look out the back window. The screen showed the car with a yellow glow where the trunk was. The trunk lid was up and it hit the garage door frame – very slightly but enough to cause $7,800 damage.
The rearview camera was actually looking at the open garage door that looked like a driveway in the early evening. The trunk lid was not open on the screen as when any of the doors are open – it just showed a yellow glow that meant nothing to me. The rear window can be open or closed – you can’t tell the difference from the driver’s seat.
