You'd think that on a website that has the word "hacker" in its title, more people would be supportive of someone "hacking" their car, but I guess there's not a lot of car people here.
The only socially appropriate ways to inconvenience other people are to build dark patterns into your app to juice subscriptions, dump VC-funded detritus on the street and call it a startup, or take their life’s work and create an algorithm to regurgitate it back to them without paying them for it. Making your car louder? That’s just rude and inconsiderate.
You know what is? The doings of obnoxious adtech people.
