I hear ya. Of course it doesn’t have to be waterproof. Just resistant because, not only are things going to get spilled in seats, but people are going to run to their car in an unexpected rainstorm and get in the car wet. All of these are just life. Perhaps the sensors has some shielding or a $5 fuse blows or the sensor shuts down until it is sufficiently dry. But a simple, predictable mistake (and it wasn’t a lot of coffee, my canister just leaked), a customer shouldn’t have to pay nearly $2000.I suspect all cars are going to have electronic parts below seat cushions for motor functions of the seat, such as heating/ventilator/lumbar/seat position etc. I doubt any car seat is going to be water/spill proof either.
I thank you for your thoughtful responses and feedback!
