I was bored so I just went out to my garage and checked this myself.

The wipers do not freeze when the MCU crashes or restarts. They continue working on the speed they were running at when the MCU crashes or restarts.

it reboots in under a minute so you can make adjustments then. mean while you keep driving or can pull over or whatever. its not like it happens all the time, once every month or so I push both toggle button and reboot it while I'm driving

Isn't having the wipers freeze for more than 5-10 seconds in heavy rain a big safety issue? Agreed that the chances of the freeze happening while there is heavy rain are rather slim, but nobody should be relying on their luck in this way.

Yeah, the context was "don't need to pull over, don't need to do anything, it's all perfectly safe".

Do the wipers really freeze, or can you just not change the mode they're set to?
