Quit comparing cars to guns. Cars are not a guaranteed protection under the Bill of Rights.
Actually you would be prone to pointing that out. Motor vehicles were not in the constitution as a right, nor was transportation of any kind mentioned. However there are more deaths caused by these items that do not have any constitutional guarantees that they refuse to regulate to save the children than firearms, of which we do have a constitutional right to possess. In short it is comparing two different items, but they are different and one is not a right and seems to be getting ignored.
