Blind people can be assholes, too.

Him being blind does not excuse him from being a rude loud mouth. Next time try saying something like.. Not trying to be rude or inconsiderate but can you please lower your voice. the whole car doesn't need to hear you.

Perhaps he's partially deaf, but by now, he oughta know nonetheless just how badly he "conversates" in several ways. He's probably been getting a lot of passes by others too afraid of making a clearly-disabled, socially-inept dude angry and even thus respond louder. But yea, no excuse for ever being rude....

I kinda need more context to judge I tell Siri to do things all the time in public no one ever says anything but I do it quietly. However idk how loud he was talking and he could have a hearing impairment as well I would air on the side of caution and stay quiet unless it became unbearably obnoxious

Maybe next time be more aware of your surroundings. That might help.
