So I guess ridding a bicycle is also a priviledge...a priviledge granted by government. That is why some folks get DUIs while riding a bike. Right?
If you get the chance to do some research you will find that movement by the public is/was a constitutional right, not a privledge. Driving in particular was converted into a privledge.
FWIW, in Texas, upon approaching a sobriety checkpoint, a driver may stop, execute a u-turn, and find a alternate route around the checkpoint in full view of law enforcement; the driver’s actions do not constitute probable cause to stop that driver.
