It is an impressive hack. But you are not building something that is useful. Build a small component that follows safety standards - this will be useful.
Yes, I understand that. And my perspective is different from your users. It is that of someone who is seeing (and attempting to help) big automotive companies. Companies in the shadow of Waymo, that had recently reached $135B valuation. It is also that of someone, who had been hacking code for medical equipment at 13, some 25 years back.
Do as you wish.
edit: correction. out of your project we are probably having more hackers that understand at least some aspect of the problem - you still might be doing something very useful.
Help automotive companies? They have been sitting idle for decades and would rather spend their resources on flashy marketing, rather than innovate.
Car companies, even luxury brands like MB, BMW, and Audi are akin to cell phone companies running Symbian, Windows Mobile, Palm OS, and Symbian before the iPhone came along.
Now we have innovators like Tesla and open source DIY stuff from comma.ai which can churn out great tech in a very short amount of time, without the need for getting a new year model vehicle.
