I wish voice assistants like Siri could just do functions that are obvious, even if it requires learning commands. Actually especially for in-car voice assistants. I should be able to do any of the critical commands like turning on wipers, etc, via voice commands without looking at a screen or even feeling around for tactile controls with a free hand. If this was reliable and consistent, even if being reliable required learning a list of commands, that’d be a big help while driving.
