Regulation making you responsible for reckless behavior before you cause an accident.

We have that. Drivers are responsible for the outcomes of their driving with licenses, insurance, a legal framework for operating vehicles, and even uniform enforcement.

What else would you add?

Adding a technical stack will lead to court cases but our current system can accomodate — we already have tons of driving modifying systems in cars and nobody blinks an eye.

The only reason this is even controversial is that it’s third party and not provided by the manufacturer.

I would suggest that we are good! The current regulatory compliance and enforcement system can accommodate this change.

The biggest question I see is insurance coverage. I could imagine insurers moving to not cover accidents during the use of aftermarket systems like this in the same way they won’t cover incidents during track use and the like.

Why bother with drink driving rules if we already have laws against reckless driving?

Is it not fundamentally the same? If not why not?

I described some of the regulation we need.

People buying these devices are simply ill-informed about the risks that they pose to other drivers and pedestrians because companies like Comma deliberately withhold the information.

And given innocent lives are at stake the onus should be on being cautious about technologies like these until they are proven.

You are right, they are not informing you during the buy process on their website but there is a tutorial you have to follow interactively, which makes a 100% sure you understand the risks and limitations. It is not like Tesla at all.

If responsibility substituted for regulation, there'd be no car regulation at all, would there?
