I agree about 'nag ' alerts which trigger every time being quite useless - if a parent is so phased out they forget their child they're probably going to tune out routine alerts as well. And yes motion sensors would be costly. So let's go even more basic. Seems like these accidents happen predominantly in rear facing car seats. So just a light at the back of the car seat which turns on when the seat belt is fastened would indicate there's a baby in it. Kinda like an "occupied" sign on airline restrooms. If the baby's seat belt is fastened it's a sure indicator there's a baby in it ( I mean who re-fastens the belt after taking their kid out lol) and the light would be visible to the driver through the rear view mirror or when they get out. Can't say much about manufacturers trying to escape liability but you're probably right about that. Apparently there is a bill being presented for a law to make all car manufacturers install alerts to check back seats but again, routine alerts are easily ignorable
