Most resistors aren't affected substantially by water, that's why you don't get the same behavior.
I was thinking about water in the connector that could feed some of the +5 V to the signal wire causing the throttle to activate.
I figure that software could be trained to identify that kind of fault ?
I'm not really sure why bike makers don't use variable resistance in throttles instead of the HAL effect.
The HAL sensor throttles do work great !!
They just have to seal up the little circuit board inside to make them waterproof.
Which reminds me.
I have yet to seal the circuit boards in all my dozen throttles.

The only thing that I can see that could be an issue with a HAL sensor is that metal particles could stick to the magnet, but even that shouldn't matter because the "sensor" (a small coil I think?) is also sealed. (or should be)
I've got HAL sensors all over my car and they just keep working regardless of salt and water.
They're just build better. Properly sealed anyway,..
When my wheel hub rusts out and falls off the car, it'll be the HAL sensor wire that keeps it connected to the rest of the car.
