Driving on the public roads is a privilege. Walking, riding a horse, or riding a bike on the public roads is a right.
Our right to keep and bear arms is analogous to the latter and not the former. Kindly don't confuse them and please don't use this fallacious argument again.
As an aside, look at what that 'driving on public roads is a privilege' has done.
For all intents and purposes, it has
limited the
right to travel freely on public roads.
And that right is becoming more and more limited to the elite, a little at a time.
I will predict that before long, older cars will be eliminated by emission regulation and insurance standards... with the supposed intent being to eliminate 'unsafe' and 'environmentally harmful' machines. But in actual effect, people who cannot afford to own a 5 year old car or newer will be forced out of the ability to own a car that can actually be driven on public roads, limiting more and more the ability to freely and independently travel distances.
As you say, you will still be free to walk, pedal, or ride a horse... as far as you like... But the ability to really travel - distances - will be ever limited to those who are approved ~and~ can afford it...
And that noose will keep tightening. That is what insurance ad regulation will predictably and ultimately give you. And what is happening to the right to free travel can be directly compared to the intent in insuring and registering arms. The exact same thing will happen.
