People get killed by changes to exhaust, height (lift kits), bumpers (bull bars in particular), etc pretty often, though. And I can imagine software changes (exhaust is part of that actually) could kill people too.
Maybe you think daytime running lights are stupid and want to disable them for instance.
Sure. Point is nothing has really changed. Largely there's no problem and to the extent that bad things happen it isn't something novel that's only just come up. It's not in and of itself an excuse to erode private ownership. If intervention is required then regulation should be passed deliberately by the legislature.
