Re:Right to travel--Your right to breathe is not being infringed, you just have to have someone jump on your chest or give you mouth-to-mouth, OR ask the state for permission to take in air under your own power.
A driver's license does NOT infringe on one's right to travel. One is free to hire transport, or walk.
The "right to travel" does not imply that a particular MODE of travel is guaranteed to you.
