I own this exact tractor

and even it has a sensor in the driver's seat that will stop it if there is less than 100 lbs in the driver's seat. (When my son weighed 80 lbs he couldn't drive it unless I put 2 10 lb weightlifting plates and put them in a backpack.)

The purpose there is so that the tractor doesn't drag or crush you if you fall out of the seat, but that kind of sensor is also commonly used in the passenger seat of cars to scale the force of the passenger side airbag to the size of the occupant.

AFAIK, Teslas do have weight sensors in the drivers seat. Now the question is, why is that not used in this scenario? A bug or some actual reason not to continuously check driver weight (=presence)?

I actually find that these nanny features can be to be annoying. My car will beep continuously if I put something in the front passenger seat but don’t buckle the seat belt, because it thinks a passenger is riding without the seat belt. I would rather it just say something once and get out of the way, letting me use my car how I want.

For my car, you can turn on the ignition and buckle/unbuckle the drivers belt 3 times in a row. Doing that turns off the constant alarm and only chimes when you first start and shows the light on the panel. Maybe your car has something similar.
