Alberta: legislated rubbernecking.

It's now an offence to drive more than 50 km/hr past emergency vehicles that, while stopped at the side of an undivided highway, have their emergency equipment activiated. Of course, this has just codified the previous popular practice of blocking traffic flow to inspect minor fender-benders, roadkill, and assorted highway detritus slowly from the safety and comfort of one's own car.
