I set up the route, clip the phone onto the quadlock mount, ride down the street and it auto changes the route because of something motorbikes don't care about.
Or it rains and that counts as pressing buttons.
And now I am riding and with gloves on so I can't fix it.
Just "do what I told you" and don't mess with it.
It doesn't fix the problem of bad software, but try adding something like https://glovetacts.com/ to your riding glove index fingers for this particular issue.
I'd love a "I saw your suggestions, I selected one of them, don't give me any more suggestions" feature. This was on google maps.
As for detecting rain, that'd be a whole other algorithm.
I'd be happy with a "phone is locked, maps is on display still, register no screen input" so nothing changes until I unlock it.
