And rightfully so, I'd add. For one, there are still far more autos on the road than bikes. And there's a lot more at stake when a 1,000+ pound vehicle with an internal combustion engine disobeys traffic laws.
Ya no one really gets it, these laws and the application/ enforcement of said laws are put in place to protect life and property. What is going to destroy more property and lives? The answer is cars, and that is why they are policed differently from bicycles. Can you imagine a cop having a bike pulled over for not stopping at a trail sign while a 3500 dually rumbles past the cop and bike that are pulled over at 70 mph in a 45 and smashes in to a kid a mile away? The outcry would be huge. How do you tell the parent of the dead kid that the cop was busy ticketing a bike or else they could have gunned the truck and pulled them over before they got to the child?
