My rental car I have right now has a huge obnoxious pop up and alarm when shutting off the vehicle saying to not forget your kids. Technology can solve this issue easily.
Constant warnings when they aren't needed just leads to them being ignored with everything else. My in law's car had one that went off every time, even when the backseat was empty. It was as easy to ignore as all of the other pointless warnings that car had.
Mine has a stupid "you are responsible for the operation of this vehicle" every time it starts up. The absolute stupidest lawyer notice ever.
Like, are you sure the driver is supposed to drive? Thanks!
