My comment is about how surprising it is something like this might be legal when other, very benign modifications are not. That was all. A whole lot more can go wrong with something like this, versus say an aftermarket exhaust.
The regulations are not hard to know, but something like Comma is a little bit in front of the regulations, and so it poses risks we have yet to discover and cater for in said regs (sensors must be weatherproof might be a good example of a good reg). The same is true for OEMs, Tesla and friends were bringing out features faster than regulations can describe if they are safe or not. This is not true for other parts of vehicles, we understand suspension safety very well so just following the regulations is enough to stay safe.
In general, unapproved vehicle modifications are a risk as they haven't gone through the same safetey and emissions appratus as approved parts and OEMs have. How risky is the variable, tires too wide, not very, full vehicle control change, pretty risky. I hold that opinion as an avid car enthusiast, some stuff we shouldn't fuck with unless we get it engineered and signed off as safe enough to join the driving public (and I have done this for my suspension modifications).
If only there was some kind of a set of rules that would define what is “ok”, it could “regulate” both manufacturers and third parties. We could call them REGULATIONS.
Or is all driving augmentation bad? Because honestly, based on the data, humans are frequently worse drivers than the absolute worst of these systems.
