Bikers who commute to the store on two wheels may be subsidizing their counterparts who choose to drive their Hummers and large SUVs to the grocery and other shopping venues. According to Bicycle Benefits Advocate Dillon Kleptetar’s excellent piece in the Sunday Washington Post’s “Local Opinions” section, drivers at grocery stores “across the nation, drivers do not bear the true economic costs of their choices, let alone the environmental ones. Instead , the supermarket takes the cost of providing the parking and, since we all pay the same prices for grocery items,” the bikers are paying for the drivers’ use of the parking lot. The bike advocate notes that “cyclists, walkers and those who take the public transit subsidize the parking of those who don’t.” I commend the rest of this piece to your consideration. Just like the “Paper or plastic” bags issue, when consumers must “foot the bill,” consideration of the environment are brought to the foreground. It makes for thought provoking reading.
