True. The oil is going to move. And oil companies are going to move it in the cheapest way possible. That means pushing any safety criteria. We didn't have double wall tankers until I think the Exxon Valdeze spill. We currently don't have adequate RR car standards : "The new standards only apply to newly manufactured cars; there is no requirement to retrofit, repurpose, or retire existing DOT-111A cars built to the older design. The NTSB has called that design "inadequate," noting the older cars are "subject to damage and catastrophic loss of hazardous materials."[32]"
Of course, the argument is "So, you'd be happy with $5 a gallon to protect a few feet of worthless soil????"
All I'd say is, we've seen oil companies shirk their responsibility to keep the product safe, which means you and I are paying for the Superfund because they never had safe storage at gas stations. 
Oh, yes I use oil. That makes me a hypocrite. Only Jesus can be critical because he's perfect.
