Speedway of the Pontiac

Highway 303 between Shawville and Portage-du-Fort may roll with the hills along its 13 km, but its speed limit of 90 km/h is not particularly excessive. Still, I keep running into drivers — at least three different drivers in recent memory — who persist in driving no more than 60 to 70 km/h along that route. It’s not that I’m surprised that there are rural drivers who go well under the speed limit, it’s that they’re turning up only on Highway 303, and nowhere else in the Pontiac. What gives, I wonder?
