Rearviews are all dimmable. Even if you don't have the button, change the pitch of your rear view slightly vertical and you'll get a dimming action. Sideview mirrors are self explanatory, just turn them out or in if it's an issue. My main thing was not risking getting in trouble to be polite when the individual you're being polite to assumes no risk or responsibility should you get in trouble. It's not being conceded or ignorant to look out for yourself first. Nobody will care about you more than you care about your own actions. Be safe, be kind, but also calculate.
