As someone who primarily rides a motorcycle for transportation, and literally has no way to interact with my phone while riding, I agree with the sentiment that this is absolutely blood boiling.
I use Google Maps by listening to the directions through a bluetooth speaker in my helmet so I rarely am ever actually looking at the screen. I absolutely hate how many times it will interrupt/announce absolutely useless information, or at times suddenly announce a route change for a 30 second faster route and it'll just sit there waiting for my input which I cannot provide in order to cancel.
Tank bag, my friend. I'd tried using voice directions, and honestly felt like throwing either my Shoei or phone off of a cliff. Granted, I mostly use navigation for longer trips, but my preferred solution is paper maps in the map compartment for highway driving. For in-town driving, I just keep a notepad in the tank bag and write down the directions. That few minutes also helps me to remember the route enough that I don't need to rely on it as much. I also find it makes riding more enjoyable, since I have one less distraction to worry about.
Plus, for longer trips paper maps are way better on a bike, since Google is really aggressive about what roads they hide. I've found way more fun roads to travel on after using this method. Plus, with a tank bag you always have your rain gear and other necessities with you. Only downside is they look ugly.
