Both of those things seem like they have a chance of splattering on the cameras.
I'm keen on trying it or getting one, but I have zero interest in using it while cooking or similar.
Although it might not matter - even cracks on a camera lens affect the picture less than you'd think, because they're out of focus.
As an alternative - would a headset lite version without the AR work better here? Display needed information on a nearby tablet or large tv while the user wears a headband only.
The windshield has a stack of huge stickers on it that get torn away by the pit crew during stops. Apparently you can get stacks up to about 20 layers.
Seems like a reasonable possibility for messy AR applications.
